Structure, business operations, subsidiary entities, and subsidiary companies [Abstract]
Structure and Business Operations of Petroleos Mexicanos, Subsidiary Entities and Subsidiary Companies	STRUCTURE AND BUSINESS OPERATIONS OF PETRÓLEOS MEXICANOS, SUBSIDIARY ENTITIES AND SUBSIDIARY COMPANIES Petróleos Mexicanos was created by a decree issued by the Mexican Congress on June 7, 1938. The decree was published in the Diario Oficial de la Federación (“Official Gazette of the Federation”) on July 20, 1938 and came into effect on that date. On December 20, 2013, the Decreto por el que se reforman y adicionan diversas disposiciones de la Constitución Política de los Estados Unidos Mexicanos, en Materia de Energía (Decree that amends and supplements various provisions of the Mexican Constitution relating to energy matters), was published in the Official Gazette of the Federation. This Decree came into effect on December 21, 2013 and includes transitional articles setting forth the general framework and timeline for implementing legislation relating to the energy sector. On August 11, 2014, the Ley de Petróleos Mexicanos (the “Petróleos Mexicanos Law”) was published in the Official Gazette of the Federation. The Petróleos Mexicanos Law became effective on October 7, 2014, except for certain provisions. On December 2, 2014, the Secretaría de Energía (“Ministry of Energy”) published in the Official Gazette of the Federation the declaration pursuant to which the special regime governing Petróleos Mexicanos’ activities relating to productive state-owned subsidiaries, affiliates, compensation, assets, administrative liabilities, state dividend, budget and debt came into effect. On June 10, 2015, the Disposiciones Generales de Contratación para Petróleos Mexicanos y sus Empresas Productivas Subsidiarias (General Contracting Provisions for Petróleos Mexicanos and its productive state-owned subsidiaries) was published in the Official Gazette of the Federation and the following day the special regime for acquisitions, leases, services and public works matters came into effect. Once the Petróleos Mexicanos Law came into effect, Petróleos Mexicanos was transformed from a decentralized public entity to a productive state-owned company. Petróleos Mexicanos is a legal entity empowered to own property and carry on business in its own name with the purpose of carrying out exploration and extraction of crude oil and other hydrocarbons in the United Mexican States (“Mexico”), as well as refining, processing, storing, transporting, selling and trading in these products. The Subsidiary Entities, Pemex Exploración y Producción (“Pemex Exploration and Production”), Pemex Transformación Industrial (“Pemex Industrial Transformation”) and Pemex Logística (“Pemex Logistics”) are productive state-owned subsidiaries empowered to own property and carry on business in their own name, subject to the direction and coordination of Petróleos Mexicanos (the “Subsidiary Entities”). The Subsidiary Entities and their primary purposes, are as follows: • Pemex Exploration and Production: This entity is in charge of the exploration and extraction of crude oil and solid, liquid or gaseous hydrocarbons in Mexico, in the exclusive economic zone of Mexico and abroad, as well as drilling services and repair and services of wells; • Pemex Industrial Transformation: This entity performs activities related to refining, transformation, processing, importing, exporting, trading and the sale of hydrocarbons, petroleum products, natural gas and petrochemicals, as well as commercializes, distributes and trades methane, ethane and propylene, directly or through others; and • Pemex Logistics: This entity provides transportation, storage and related services for crude oil, petroleum products and petrochemicals to PEMEX (as defined below) and other companies, through pipelines and maritime and terrestrial means, and provides guard and management services. The principal distinction between the Subsidiary Entities and the Subsidiary Companies (as defined below) is that the Subsidiary Entities are productive state-owned entities, whereas the Subsidiary Companies are affiliate companies that were formed in accordance with the applicable laws of each of the respective jurisdictions in which they were incorporated. The “Subsidiary Companies” are defined as those companies which are controlled, directly or indirectly, by Petróleos Mexicanos. “Associates,” as used herein, means those companies in which Petróleos Mexicanos has significant influence but not control or joint control over its financial and operating policies. Petróleos Mexicanos, the Subsidiary Entities and the Subsidiary Companies are referred to collectively herein as “PEMEX”. PEMEX’s address and its principal place of business is: Av. Marina Nacional No. 329, Col. Verónica Anzures, Alcaldía Miguel Hidalgo, 11300, Ciudad de México, México.

Disclosure of basis of preparation [Abstract]
Authorization and Basis of Preparation	AUTHORIZATION AND BASIS OF PREPARATION Authorization On April 21, 2023, these consolidated financial statements and the notes hereto were authorized for issuance by the following officers: Mr. Octavio Romero Oropeza, Chief Executive Officer, Lic. Carlos Fernando Cortez Gonzalez, Acting Chief Financial Officer, Mr. Jose Maria del Olmo Blanco, Deputy Director of Budgeting and Accounting, and Mr. Oscar René Orozco Piliado, Associate Managing Director of Accounting. These consolidated financial statements and the notes hereto are issued pursuant to the terms of Article 13 Fraction VI of the Petróleos Mexicanos Law, Article 104 Fraction III, paragraph a, of the Ley del Mercado de Valores (Securities Market Law), and of Article 33 Fraction I, paragraph a, section 3 and Article 78 of the Disposiciones de carácter general aplicables a las emisoras de valores y a otros participantes del mercado de valores (“General provisions applicable to securities’ issuers and other participants of the securities market”). Basis of preparation A. Statement of compliance PEMEX prepared its consolidated financial statements as of December 31, 2022 and 2021, and for the years ended December 31, 2022, 2021 and 2020, in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). B. Basis of accounting These consolidated financial statements have been prepared using the historical cost basis method, with the exception of the following items, which have been measured using an alternative basis. ITEM BASIS OF MEASUREMENT Derivative Financial Instruments (“DFIs”) Fair Value Employee Benefits Fair Value of plan assets less present value of the obligation (defined benefit plan) C. Going concern The consolidated financial statements have been prepared on a going concern basis, which assumes that PEMEX will be able to continue its operations and can meet its payment obligations for a reasonable period (See Note 22-F). D. Functional and reporting currency These consolidated financial statements are presented in Mexican pesos, which is both PEMEX’s functional currency and reporting currency, due to the following: i. The economic environment in which PEMEX operates is Mexico, where the legal currency is the Mexican peso; ii. The budget through which Petróleos Mexicanos and its Subsidiary Entities operate as entities of the Mexican Government, including the ceiling for personnel services, is elaborated, approved and exercised in Mexican pesos; iii. Employee benefits provision was 33% and 33% of PEMEX’s total liabilities as of December 31, 2022 and 2021, respectively. This provision is computed, denominated and payable in Mexican pesos; and iv. Cash flows for payment of general expenses, taxes and duties are realized in Mexican pesos. Although the sales prices of certain products are based on international U.S. dollar-indices, final domestic selling prices are governed by the economic and financial policies established by the Mexican Government. Accordingly, cash flows from domestic sales are generated and received in Mexican pesos. With regards to PEMEX’s foreign currency (export sales, borrowings, etc.), Mexico’s monetary policy regulator, the Banco de México (“Mexican Central Bank”), requires that Mexican Government entities other than financial entities sell their foreign currency to the Mexican Central Bank in accordance with its terms, receiving Mexican pesos in exchange, which is the currency of legal tender in Mexico. Terms definition References in these consolidated financial statements and the related notes to “pesos” or “Ps.” refers to Mexican pesos, “U.S. dollars” or “U.S.$” refers to dollars of the United States of America, “yen” or “¥” refers to Japanese yen, “euro” or “€” refers to the legal currency of the European Economic and Monetary Union, “pounds sterling” or “£” refers to the legal currency of the United Kingdom and “Swiss francs” or “CHF” refers to the legal currency of the Swiss Confederation. Figures in all currencies are presented in thousands of the relevant currency unit, except exchange rates and product and share prices. E. Use of judgments and estimates The preparation of the consolidated financial statements in accordance with IFRS requires the use of estimates and assumptions made by PEMEX’s management that affect the recorded amounts of assets and liabilities and the disclosures of contingent assets and liabilities as of the date of these consolidated financial statements, as well as the recorded amounts of income, costs and expenses during the year. Actual results may differ from these estimates. Significant estimates and underlying assumptions are reviewed, and the effects of such revisions are recognized in the years in which any estimates are revised and in any future periods affected by such revision. Information about estimates, assumptions and critical accounting policies that have the most significant effects on the amounts recognized in the consolidated financial statements are described in the following notes: i. Judgments, assumptions and estimation uncertainties • Note 3-A-i Basis of consolidation – Business combination • Note 3-C Financial instruments – Fair Value and expected credit losses. • Note 3-E Wells, pipelines, properties, plant and equipment – Useful lives. • Note 3-F Intangible assets, wells not assigned to a reserve and oil and natural gas exploration and license, appraisal and development expenditure – successful efforts method. • Note 3-H Impairment of non-financial assets – fair values, cash flow estimates and discount rates determination. • Note 3-I Leases – Early cancellation or renewal options. • Note 3-J Provisions – Environmental liabilities and retirement of assets. • Note 3-K Employee benefits – Actuarial assumptions. • Note 3-L Income taxes, duties and royalties – Recoverability assessment of deferred tax assets. • Note 3-M Contingencies – Probability assessment. • Note 3-P – Revenue from contracts with customers ii. Measurement of fair values Some of PEMEX’s accounting policies and disclosures require the measurement of the fair values of financial assets and liabilities, as well as non-financial assets and liabilities. PEMEX has an established control framework with respect to the measurement of fair values. This includes a valuation team that has overall responsibility for overseeing all significant fair value measurements, including Level 3 fair values. The valuation team regularly reviews significant unobservable inputs and valuation adjustments. If third party information, such as broker quotes or pricing services, is used to measure fair values, then the valuation team assesses the evidence obtained from the third parties to support the conclusion that these valuations meet the requirements of IFRS, including the level in the fair value hierarchy in which the valuations should be classified. When measuring the fair value of an asset or a liability, PEMEX uses market observable data as far as possible. Fair values are categorized into different levels in a fair value hierarchy based on the inputs used in the valuation techniques as follows. • Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities. • Level 2: inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly (i.e., as prices) or indirectly (i.e., derived from prices). • Level 3: inputs for the asset or liability that are not based on observable market data (unobservable inputs). If the inputs used to measure the fair value of an asset or a liability might be categorized in different levels of the fair value hierarchy, then the fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level input that is significant to the entire measurement. PEMEX recognizes transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred. F. Convenience translations These consolidated financial statements are presented in Mexican pesos (reporting currency), which is the same as the recording currency and the functional currency of PEMEX. The U.S. dollar amounts shown in the consolidated statements of financial position, the consolidated statements of comprehensive income, the consolidated statements of changes in equity (deficit) and the consolidated statements of cash flows have been included solely for the convenience of the reader and are unaudited. Such amounts have been translated from amounts in pesos, as a matter of arithmetic computation only, at the exchange rate for the settlement of obligations in foreign currencies provided by the Mexican Central Bank and the Secretaría de Hacienda y Crédito Público (“Ministry of Finance and Public Credit” or “SHCP”) at December 31, 2022 of Ps. 19.4143 per U.S. dollar. Translations herein should not be construed as a representation that the peso amounts have been or could be converted into U.S. dollars at the foregoing or any other rate.

Significant Accounting Policies

Significant Accounting Policies	12 Months Ended

Disclosure of voluntary change in accounting policy [abstract]
Significant Accounting Policies	SIGNIFICANT ACCOUNTING POLICIES PEMEX has consistently applied the following accounting policies to each of the periods presented in the preparation of its consolidated financial statements. Below is a summary of the principal accounting policies: A. Basis of consolidation The consolidated financial statements include the financial statements of Petróleos Mexicanos and those of its subsidiaries over which it has control. i. Business combinations PEMEX accounts for business combinations using the acquisition method when the acquired set of activities and assets meets the definition of a business and control is transferred to PEMEX. In determining whether a particular set of activities and assets is a business, PEMEX assesses whether the set of assets and activities acquired includes, at a minimum, an input and substantive process and whether the acquired set could produce outputs. PEMEX has an option to apply a ‘concentration test’ that permits a simplified assessment of whether an acquired set of activities and assets is not a business. The optional concentration test is met if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. The consideration transferred in the acquisition is generally measured at fair value, as are the identifiable net assets acquired. Any goodwill that arises is tested annually for impairment. Any gain on a bargain purchase is recognized in profit or loss immediately. Transaction costs are expensed as incurred, except if related to the issue of debt or equity securities. Any contingent consideration is measured at fair value at the date of acquisition. If an obligation to pay contingent consideration that meets the definition of a financial instrument is classified as equity, then it is not remeasured and settlement is accounted for within equity. Otherwise, other contingent consideration is remeasured at fair value at each reporting date and subsequent changes in the fair value of the contingent consideration are recognized in profit or loss. ii. Subsidiaries Subsidiaries are entities controlled by PEMEX. PEMEX “controls” an entity when it is exposed to, or has rights to, variable returns from its involvement with the entity and could affect those returns through its power over the entity. The financial statements of subsidiaries are included in the consolidated financial statements from the date on which control commences until the date on which control ceases. For more information about the Subsidiary Companies, see Note 5. iii. Non-controlling interests (NCI) NCI are measured initially at their proportionate share of the acquiree’s identifiable net assets at the date of acquisition. Changes in the ownership interest in a subsidiary that do not result in a loss of control are accounted for as equity transactions. iv. Loss of control When PEMEX loses control over a subsidiary, it derecognizes the assets and liabilities of the subsidiary, and any related NCI and other components of equity. Any resulting gain or loss is recognized in profit or loss. Any interest retained in the former subsidiary is measured at fair value when control is lost. v. Interests in equity-accounted investees PEMEX’s interests in equity-accounted investees comprise interests in associates and a joint venture. Associates are those entities in which PEMEX has significant influence, but not control or joint control, over the financial and operating policies. A joint venture is an arrangement in which PEMEX has joint control, whereby PEMEX has rights to the net assets of the arrangement, rather than rights to its assets and obligations for its liabilities (joint operation). Interests in associates and the joint venture are accounted for using the equity method. They are initially recognized at cost, which includes transaction costs. Subsequent to initial recognition, the consolidated financial statements include PEMEX’s share of the profit or loss and other comprehensive income (OCI) of equity accounted investees, until the date on which significant influence or joint control ceases. Upon loss of significant influence over the associate or joint control over the joint venture, PEMEX measures and recognizes any retained investment at its fair value. Any difference between the carrying amount of the associate or joint venture upon loss of significant influence or joint control and the fair value of the retained investment and proceeds from disposal is recognized in profit or loss. When the value of the share of losses exceeds the value of PEMEX’s investment in an associate or joint venture, the carrying value of the investment, including any long-term investment, is reduced to zero and PEMEX ceases to recognize additional losses, except in cases where PEMEX is liable for obligations incurred by those associates and joint ventures. For more information about joint ventures and associates, see Note 12. vi. Transactions eliminated on consolidation Intra-group balances and transactions, and any unrealized income and expenses arising from intra-group transactions, are eliminated. Unrealized gains arising from transactions with equity-accounted investees are eliminated against the investment to the extent of the PEMEX interest in the investee. Unrealized losses are eliminated in the same way as unrealized gains, but only to the extent that there is no evidence of impairment. B. Foreign currency i. Foreign currency transactions Transactions in foreign currencies are translated into the respective functional currencies of PEMEX companies at the exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency at the exchange rate at the reporting date. Non-monetary assets and liabilities that are measured at fair value in a foreign currency are translated into the functional currency at the exchange rate when the fair value was determined. Non-monetary items that are measured based on historical cost in a foreign currency are translated at the exchange rate at the date of the transaction. Foreign currency differences are generally recognized in consolidated statements of comprehensive income and presented within foreign exchange. ii. Foreign operation The financial statements of foreign subsidiaries and associates are translated into the reporting currency by first identifying if the functional currency is different from the currency for recording the foreign operations, and, if so, the recording currency is translated into the functional currency and then into the reporting currency using the year-end exchange rate of each period for assets and liabilities reported in the consolidated statements of financial position; the historical exchange rate at the date of the transaction for equity items; and the exchange rate at the date of the transaction for income and expenses reported in the consolidated statement of comprehensive income. Foreign currency differences are recognized in OCI and accumulated in the currency translation effect, except to the extent that the translation difference is allocated to NCI. When a foreign operation is disposed of in its entirety or partially such that control, significant influence or joint control is lost, the cumulative amount in the translation reserve related to that foreign operation is reclassified to the consolidated statement of comprehensive income as part of the gain or loss on disposal. If PEMEX disposes of part of its interest in a subsidiary but retains control, then the relevant proportion of the cumulative amount is reattributed to NCI. When PEMEX disposes of only part of an associate or joint venture while retaining significant influence or joint control, the relevant proportion of the cumulative amount is reclassified to profit or loss. C. Financial instruments i. Recognition and initial measurement Financial assets and liabilities are initially recognized when these assets are contractually originated or acquired, or when these liabilities are contractually issued or assumed. Financial assets and financial liabilities (unless it is an account receivable or account payable without a significant financing component) are measured and initially recognized at fair value, in the case of financial assets or liabilities not measured at fair value with changes through OCI, plus the transaction costs directly attributable to acquisition or issuance, when subsequently measured at amortized cost. An account receivable or account payable without a significant financing component is initially measured at the transaction price. If PEMEX determines that the fair value at the initial recognition differs from the transaction price, PEMEX shall recognize the difference between the fair value at initial the recognition and the transaction price in the consolidated statements of comprehensive income. ii. Classification and subsequent measurement Financial Assets On initial recognition, a financial asset is classified as measured at: Amortized Cost; Fair Value Through Other Comprehensive Income (“FVTOCI”)–debt investment; FVTOCI–equity investment; or Fair Value Through Profit or Loss (“FVTPL”). Financial assets are not reclassified subsequent to their initial recognition unless PEMEX changes its business model for managing financial assets, in which case all affected financial assets are reclassified on the first day of the first reporting period following the change in the business model. FINANCIAL ASSETS MEASUREMENT Amortized cost A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as at FVTPL: •   it is held within a business model that has the objective of holding assets to collect contractual cash flows; and •   its contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. Debt investment A debt instrument is measured at FVTOCI only if it meets both of the following conditions and is not designated as at FVTPL: •   it is held within a business model that has the objective of both collecting contractual cash flows and selling financial assets; and •   its contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. Equity investment On initial recognition of an equity investment that is not held for trading, PEMEX may irrevocably elect to present subsequent changes in fair value in OCI. This election is made on an investment-by-investment basis. All financial assets not classified as measured at amortized cost or FVTOCI (as described above) are measured at FVTPL. This includes all derivative financial assets (see Note 18). On initial recognition, PEMEX may irrevocably designate a financial asset that otherwise meets the requirements to be measured at amortized cost or at FVOCI as FVTPL, if doing so eliminates or significantly reduces an accounting mismatch that would otherwise arise. Financial assets: Business model assessment PEMEX assesses the objective of the business model in which a financial asset is held at a portfolio level because this best reflects the way the business is managed and information is provided to management. The information considered includes: • the stated policies and objectives for the portfolio and the operation of those policies in practice, which include whether management’s strategy focuses on earning contractual interest income, maintaining a particular interest rate profile, matching the duration of the financial assets to the duration of any related liabilities or expected cash outflows or realizing cash flows through the sale of the assets; • how the performance of the portfolio is evaluated and reported to PEMEX management; • the risk that affects the performance of the business model (and the financial assets held within that business model) and how those risks are managed; • how managers of the business are compensated (e.g., whether compensation is based on the fair value of the assets managed or the contractual cash flows collected); and • the frequency, volume and timing of sales in prior periods, the reasons for such sales and expectations about future sales activity. Transfers of financial assets to third parties in transactions that do not qualify for derecognition are not considered sales for this purpose, consistent with PEMEX’s continuing recognition of the assets. Financial assets that are held for trading or managed and the performance of which is evaluated on a fair value basis are measured at FVTPL. Financial Asset: Assessment whether contractual cash flows are solely payments of principal and interest For the purposes of this assessment, principal is defined as the fair value of the financial assets on initial recognition. Interest is defined as consideration for the time value of money and for the credit risk associated with the principal amount outstanding during the relevant period of time and for the basic lending risks and costs (e.g., liquidity risk and administrative costs), as well as profit margin. In assessing whether the contractual cash flows are solely payments of principal and interest, PEMEX considers the contractual terms of the instrument, which includes assessing whether the financial asset contains a contractual term that could change the timing or amount of contractual cash flows such that it would not meet this condition. In making this assessment, PEMEX considers: • contingent events that would change the amount or timing of cash flows; • terms that may adjust the contractual coupon rate, including variable rate features; • prepayment and extension features; and • terms that limit PEMEX’s claim to cash flows from specified assets (for example, non-recourse features). A prepayment feature is consistent solely with the payments of principal and interest criterion if the prepayment amount substantially represents unpaid amounts of principal and interest on the principal amount outstanding, which may include reasonable additional compensation for early termination of the contract. Additionally, for a financial asset acquired at a significant discount or premium to its contractual par amount, a feature that permits or requires prepayment at an amount that substantially represents the contractual par amount plus accrued (but unpaid) contractual interest (which may also include reasonable additional compensation for early termination) is treated as consistent with this criterion if the fair value of the prepayment feature is insignificant at initial recognition. Financial assets: Subsequent measurement and gain and losses Financial assets at FVTPL Financial assets at FVTPL are measured at fair value and changes therein, including any interest or dividend income, are recognized in profit or loss. Financial assets at amortized cost These assets are subsequently measured at amortized cost using the effective interest method. The amortized cost is reduced by impairment losses. Interest income, foreign exchange gains and losses and impairment are recognized in profit or loss. Any gain or loss on derecognition is recognized in profit or loss. Debt investments at FVOCI These assets are subsequently measured at fair value. Interest income calculated using the effective interest method, foreign exchange gains and losses and impairment are recognized in profit or loss. Other net gains and losses are recognized in OCI. On derecognition, gains and losses accumulated in OCI are reclassified to profit or loss. Equity investments at FVOCI These assets are subsequently measured at fair value. Dividends are recognized as income in profit or loss unless the dividend clearly represents a recovery of part of the cost of the investment. Other net gains and losses are recognized in OCI and are never reclassified to profit or loss. Financial liabilities: Classification, subsequent measurement and gains and losses Financial liabilities are classified as measured at amortized cost or FVTPL. A financial liability is classified as FVTPL if it is classified as held-for-trading, it is a derivative or it is designated as such on initial recognition. Financial liabilities at FVTPL are measured at fair value and net gains and losses, including any interest expense, are recognized in profit or loss. Other financial liabilities are subsequently measured at amortized cost using the effective interest method. Interest expense and foreign exchange gains and losses are recognized in profit or loss. Any gain or loss on derecognition is also recognized in profit or loss. iii. Derecognition Financial assets PEMEX derecognizes a financial asset when the contractual rights to the cash flows from the financial asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all of the risks and rewards of ownership of the financial asset are transferred or in which PEMEX neither transfers nor retains substantially all of the risks and rewards of ownership and it does not retain control of the financial asset. PEMEX enters into transactions whereby it transfers assets recognized in its statement of financial position but retains either all or substantially all of the risks and rewards of the transferred assets. In these cases, the transferred assets are not derecognized. Financial liabilities PEMEX derecognizes a financial liability when its contractual obligations are discharged, cancelled or expired. PEMEX also derecognizes a financial liability when its terms are modified and the cash flows of the modified liability are substantially different, in which case a new financial liability based on the modified terms is recognized at fair value. On derecognition of a financial liability, the difference between the carrying amount extinguished and the consideration paid (including any non-cash assets transferred or liabilities assumed) is recognized in profit or loss. Interest rate benchmark reform When the basis for determining the contractual cash flows of a financial asset or financial liability measured at amortized cost changed as a result of interest rate benchmark reform, PEMEX updated the effective interest rate of the financial asset or financial liability to reflect the change that is required by the reform. A change in the basis for determining the contractual cash flows is required by interest rate benchmark reform if the following conditions are met: • the change is necessary as a direct consequence of the reform; and • the new basis for determining the contractual cash flows is economically equivalent to the previous basis – i.e., the basis immediately before the change. When changes are made to a financial asset or financial liability in addition to changes to the basis for determining the contractual cash flows required by interest rate benchmark reform, PEMEX first updates the effective interest rate of the financial asset or financial liability to reflect the change that is required by interest rate benchmark reform. After that, PEMEX applies the policies on accounting for modifications to the additional changes. iv. Offsetting Financial assets and financial liabilities are offset, and the net amount is presented in the statement of financial position when, and only when, PEMEX has a legally enforceable right to set off the amounts and it intends either to settle them on a net basis or to realize the asset and settle the liability simultaneously. v. Derivative financial instruments and hedge accounting PEMEX uses DFIs to hedge the risk exposure in foreign currency, interest rate and the price of commodities related to its products. Embedded derivatives are separated from the host contract and accounted for separately if the host contract is not a financial asset and certain criteria are met. These contracts are not accounted as designated hedging instruments. DFIs are accounted for as financial assets when the fair value is positive and as a financial liability when the fair value is negative. vi. Impairment Financial instruments and contract assets PEMEX recognizes loss allowances for Estimated Credit Losses (“ECLs”) on: • financial assets measured at amortized cost; • debt investments measured at FVOCI; and • contract assets. PEMEX measures loss allowances at an amount equal to lifetime ECL, except for the following, which are measured as 12-month ECLs: • debt securities that are determined to have low credit risk at the reporting date; and • other debt securities and bank balances for which credit risk (i.e., the risk of default occurring over the expected life of the financial instrument) has not increased significantly since initial recognition. PEMEX considers a financial asset to be in default when the debtor is unlikely to pay its credit obligations to PEMEX in full, without recourse by PEMEX to actions such as guarantee redemption (if any is held). PEMEX considers that a debt instrument has a low credit risk, when its credit rating is classified as “investment grade.” The investment grade classification is based on minimum credit ratings of Baa3 (Moody’s) and BBB- (S&P and Fitch), as well as its equivalent in other rating agencies. Lifetime ECLs are the credit losses that result from all possible default events over the expected life of a financial instrument. 12-month ECLs are the portion of ECLs that result from default events that are possible within the 12 months after the reporting date (or a shorter period if the expected life of the instrument is less than 12 months). The maximum period considered when estimating ECLs is the maximum contractual period over which PEMEX is exposed to credit risk. Measurement of ECLs ECLs are a probability-weighted estimate of credit losses. Credit losses are measured as the present value of all cash shortfalls (for example, the difference between the cash flows due to the entity in accordance with the contract and the cash flows that PEMEX expects to receive). ECLs are discounted at the effective interest rate of the financial asset. Credit-impaired financial assets At each reporting date, PEMEX assesses whether financial assets carried at amortized cost and debt securities at FVOCI are credit-impaired. A financial asset is ‘credit-impaired’ when one or more events that have a detrimental impact on the estimated future cash flows of the financial asset have occurred. Evidence that a financial asset is credit-impaired includes the following observable data: • significant financial difficulty of the borrower or issuer; • a breach of contract such as a default or being more than 90 days past due; • the restructuring of a loan or advance by PEMEX on terms that it would not consider otherwise; • it is probable that the borrower will enter bankruptcy or other financial reorganization; or • the disappearance of an active market for a security because of financial difficulties. Presentation of allowance for ECL in the statement of financial position Loss allowances for financial assets measured at amortized cost are deducted from the gross carrying amount of the assets. Write-off The gross carrying amount of a financial asset is written off when PEMEX has no reasonable expectation of recovering a financial asset in its entirety or a portion thereof. In the case of individual customers, PEMEX’s policy is to cancel the gross carrying amount when the financial asset has met the uncollectibility report as established in the Políticas Generales y Procedimientos para Cancelar Adeudos (Procedure to Write-Off Financial Assets). For corporate customers, PEMEX individually makes an assessment with respect to the timing and amount of write-off based on whether there is a reasonable expectation of recovery. However, financial assets that are written off could still be subject to enforcement activities in order to comply with the PEMEX’s procedures for recovery of amounts due. D. Inventories and cost of sales Inventories are valued at the lower of cost or net realizable value. Cost is determined based on the cost of production or acquisition of inventory and other costs incurred in transporting such inventory to its present location and in its present condition, using the average cost method. Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated selling costs. The estimate takes into consideration, among other things, the decrease in the value of inventories due to obsolescence. Cost of sales represents the cost of production or acquisition of inventories at the time of sale, increased, where appropriate, by declines in net realizable value of inventories during the year. Advance payment to suppliers for inventory purchases are recognized as part of inventory when the risks and benefits of the ownership of the inventory have been transferred to PEMEX. E. Wells, pipelines, properties, plant and equipment i. Recognition and measurement Items of wells, pipelines, properties, plant and equipment are recorded at acquisition or construction cost, which includes capitalized borrowing cost, less accumulated depreciation and accumulated impairment losses. Initial costs of wells, pipelines, properties, plant and equipment are initially recorded at cost, which includes their original purchase price or construction cost, any costs attributable to bringing the assets to a working condition for their intended use and the costs of dismantling and removing the items and restoring the site on which they are located, including the estimated cost of plugging and abandoning wells. The cost of financing projects that require large investments and financing incurred for projects, net of interest revenues from the temporary investment of these funds, is recognized as part of wells, pipelines, properties, plant and equipment when the cost is directly attributable to the construction or acquisition of a qualifying asset. The capitalization of these costs is suspended during periods in which the development of construction is interrupted, and its capitalization ends when the activities necessary for the use of the qualifying asset are substantially completed. All other financing costs are recognized in the consolidated statements of comprehensive income in the period in which they are incurred. The cost of self-constructed assets includes the cost of materials and direct labor, interest on financing and any other costs directly attributable to start up. In some cases, the cost also includes costs of plugging of wells and removal at present value. Expenditures related to the construction of wells, pipelines, properties, plant and equipment during the stage prior to commissioning are stated at cost as intangible assets or construction in progress, in accordance with the characteristics of the asset. Once the assets are ready for use, they are transferred to the respective component of wells, pipelines, properties, plant and equipment and depreciation or amortization begins. If significant parts of an item of wells, pipelines, properties, plant and equipment have different useful lives, then they are accounted for as separate items (major components) of property, plant and equipment. Any gain or loss on disposal of an item of wells, pipelines, properties, plant and equipment is recognized in profit or loss. Advance payments for the acquisition of pipelines, properties, plant and equipment are also recognized in the line item of wells, pipelines, properties, plant and equipment when the risks and benefits of the ownership have been transferred to PEMEX. ii. Subsequent expenditure The costs of major maintenance or replacement of a significant component of an item of wells, pipelines, properties, plant and equipment are recognized in the carrying amount of the item if it is probable that the future economic benefits embodied within the component will flow to PEMEX and its cost can be measured reliably. The costs of recurring maintenance, repairs and renovations of wells, pipelines, properties, plant and equipment carried out to maintain the facilities in normal operation conditions are recognized in profit or loss as incurred. iii. Depreciation Depreciation and amortization of capitalized costs in wells are determined based on the estimated economic life of the field to which the wells belong, considering the relationship between the production of barrels of oil equivalent for the period and proved developed reserves of the field, as of the beginning of the period, with quarterly updates for new development investments. Depreciation of other elements of pipelines, properties, plant and equipment is recognized in profit or loss on a straight-line basis over the estimated useful life of the asset, beginning as of the date that the asset is available for use, or in the case of construction, from the date that the asset is completed and ready for use. The estimated useful lives of wells, pipelines, properties, plant and equipment for current and comparative periods are described in Note 13. Estimated useful lives of items of properties, plant and equipment are reviewed and updated prospectively if expectations differ from previous estimates. F. Intangible assets and oil and natural gas exploration and license, appraisal and development expenditure i. Intangible assets Intangible assets acquired separately are measured at initial recognition at their acquisition cost. After the initial recognition, intangible assets are valued at their acquisition cost, less: (i) accumulated amortization, under the straight-line method during the estimated useful life of the intangible asset and (ii) accumulated impairment losses. Subsequent expenditure is capitalized only when it increases the future economic benefits embodied in the specific asset to which it relates. All other expenditure is recognized in profit or loss as incurred. Amortization is calculated to write off the cost of intangible assets less their estimated residual values using the straight-line method over their estimated useful lives and is generally recognized in profit or loss. Software licenses are amortized over the lesser of their contract period or the remaining life of the asset to which they are associated. The estimated useful lives of elements of intangible assets for current and comparative periods are described in Note 14. The estimated useful lives and residual values of intangible assets are reviewed at each reporting date and adjusted if appropriate. ii. Wells not assigned to a reserve, oil and natural gas exploration, appraisal and development expenditure a. Wells not assigned to a reserve Wells not assigned to a reserve mainly include drilling, evaluation and development costs for oil and natural gas, and rights-of-way. b. Oil and natural gas exploration, appraisal and development expenditures Oil and natural gas exploration, evaluation and development expenses are accounted for using the principles of the successful efforts method of accounting, as described below: Successful Efforts Method Pemex Exploration and Production applies IFRS 6 - Exploration and Evaluation of Mineral Resources, which allows an entity to develop an accounting policy for exploration and evaluation assets. Therefore, Pemex Exploration and Production uses the method of successful efforts, which requires a cause-and-effect relationship between the costs incurred and the recognition of specific reserves. Generally, if a cost is incurred without an identifiable future benefit, it is charged to expenses. Before PEMEX is able to determine the accounting treatment of a cost, it must be classified as a property acquisition, exploration, development or production cost. Exploration and appraisal expenditure Geological and geophysical exploration costs including topographic costs, geological studies, property access rights, remuneration and expenses of geologists and geophysicists are charged to expenses as incurred. Costs directly associated with an exploration well, other than the costs mentioned in the preceding paragraph, are initially capitalized as an intangible asset (wells not assigned to a reserve) until the drilling of the well is complete and the results have been evaluated. These costs include employee compensation, materials and fuel used, platform costs and payments made to contractors. If potentially commercial quantities of hydrocarbons are not found, the exploration well costs are written off against profit or loss. If hydrocarbons are found and, subject to additiona

Segment Financial Information	SEGMENT FINANCIAL INFORMATION PEMEX’s primary business is the exploration and production of crude oil and natural gas, as well as the production, processing, marketing and distribution of petroleum and petrochemical products. As of December 31, 2022, and 2021, PEMEX’s operations were conducted through The primary sources of revenue for PEMEX’s business segments are as described below: • The exploration and production segment earns revenues from domestic sales of crude oil and natural gas, and from exporting crude oil through certain of the Trading Companies. Crude oil export sales are made through the agent subsidiary company PMI CIM, to 17 major customers in various foreign markets. Approximately half of PEMEX’s crude oil is sold to Pemex Industrial Transformation. Additionally, it receives income from drilling services, and servicing and repairing wells. • The industrial transformation segment earns revenues from sales of refined petroleum products and derivatives, mainly to third parties within the domestic market. This segment also sells a significant portion of the fuel oil it produces to the Comisión Federal de Electricidad (Federal Eletricity Commission, or “CFE”) and a significant portion of jet fuel produced to the Aeropuertos y Servicios Auxiliares (Airports and Auxiliary Services Agency or "ASA"). The refining segment’s most important products are different types of gasoline and diesel. • The industrial transformation segment also earns revenues from domestic sources generated by sales of natural gas, liquefied petroleum gas, naphtha, butane and ethane and certain other petrochemicals such as methane derivatives, ethane derivatives, aromatics, ammonia, fertilizers and its derivatives. • The logistics segment earns income from transportation and storage of crude oil, petroleum products and petrochemicals, as well as related services, which it provides by employing pipelines and offshore and onshore resources, and from providing services related to the maintenance, handling, guarding and management of these products. • Effective January 20, 2022, the Deer Park segment includes DPRLP's operations, whose operating results and performance are currently and regularly reviewed as a separate business by PEMEX's Board of Directors. DPRLP generates revenues from sales of distillates and gasoline in the U.S. market. • The trading companies segment, which consist of PMI CIM, PMI NASA, PMI Trading and MGAS (the “Trading Companies”), earns revenues from trading crude oil, natural gas and petroleum and petrochemical products in international markets. • The segment related to corporate provides administrative, financing and consulting services to PEMEX’s subsidiary entities and companies. • The segment related to the Subsidiary Companies provides administrative, financing, consulting and logistical services, as well as economic, tax and legal advice and re-insurance services to PEMEX’s subsidiary entities and companies.

Nature, performance obligations and timing of revenue recognition- Revenue is measured based on the consideration specified in a contract with a customer. PEMEX recognizes revenue when it transfers control over a good or service to a customer. The following table provides information about the nature and timing of the satisfaction of performance obligations in contracts with customers, including significant payment terms and the related revenue. Products / services Nature, performance obligations Timing of revenue recognition Crude oil sales Export sales of crude oil are based on delivery terms established in contracts or orders. All sales are performed by the Free on Board International commercial term (“FOB” Incoterm). Crude oil sale contracts consider possible customers’ claims due to product quality, volume or delays in boarding, which are estimated in the price of the transaction. For orders that have variations in price, revenue is adjusted on the closing date of each period. The subsequent variations in the fair value at the different reporting dates are recognized according to IFRS 9. The price of the product is determined based on a market components formula and the sale of crude oil. Revenue is recognized at a point in time when control of the crude oil has transferred to the customer, which occurs when the product is delivered at the point of shipping. Invoices are generated at that time and are mostly payable within the deadlines established in contracts or orders. Payments in respect of crude oil sold and delivered shall be made within 30 days after the date of the bill of lading therefor. For international market crude oil sales, revenue is recognized with a provisional price, which undergoes subsequent adjustments until the product has arrived at the port of destination. There may be a period of up to two months in determining the final sale price, such as in the case of sales to some regions. Revenue is measured initially estimating variables such as quality and volume claims, delays in boarding, etc. Sale of petroleum products For all petroleum products, there is only one performance obligation that includes transport and handling services to the point of delivery. The price is determined based on the price at the point of delivery, adding the price of the services rendered (freight, handling of jet fuel, etc.) with the provisions and terms established by the Comisión Reguladora de Energía (Energy Regulatory Commission or “CRE”). Revenue is recognized at a point in time when control is transferred to the customer, which occurs either at the point of shipping or when it is delivered at the customer’s facilities. Therefore, transportation fees can be included in the price of sale of the product and are considered part of a single performance obligation since transportation is rendered before control is transferred. Revenue is initially measured by estimating variables such as quality and volume claims, etc. Invoices are usually payable within 30 days. Sales of natural gas There is only one performance obligation that includes transport and handling services to the point of delivery. The transaction price is established at the time of sale, including the estimation of variable considerations such as capacity, penalties, adjustments for quality or volume claims, and incentives for the purchase of products; which are known days after the transaction. Such variable consideration is recognized to the extent that it is probable that it will not be reversed in a future period. Revenue is recognized at a point in time when control is transferred to the customer, which occurs when it is delivered at the customer’s facilities. Therefore, transportation fees can be included in the price of sale of the product and are considered part of a single performance obligation since transportation is rendered before control is transferred. Revenue initially is measured estimating variables as quality and volume claims, etc. Invoices are usually payable within 30 days. Services In cases where within the same service order there are transportation and storage services, there could exist more than one performance obligation, depending on the term of the service. When there is a performance obligation, the price is not distributed, but if it is considered that there is more than one performance obligation, the price of the transaction is considered based on the prices established in the service orders and which also include penalties such as quality and volume claims. Income is recognized over time as the service is rendered. Invoices are usually payable within 22 days. Other products There is only one performance obligation that includes transportation for delivery to destination. The sale and delivery of the product are made at the same time and because they are FOB, transportation fees are included in the price of sale of the product. The transaction price is established at the time of sale, including the estimation of variable considerations such as capacity, penalties, extraordinary sales not included in contracts, adjustments for quality or volume claims, and incentives for the purchase of products; which are known days after the transaction. The price of the product is estimated on the date of sale and considers variables such as quality and volume claims, etc. Invoices are usually payable within 30 days. B. Accounts receivable in the statement of financial position As of December 31, 2022 and 2021, PEMEX had accounts receivable derived from customer contracts in the amounts of Ps. 107,117,145 and Ps. 101,259,081, respectively (see Note 10). As of December 31, 2022 and 2021, advance of customers was Ps. 39,465,014 and Ps. 7,495,198, respectively of which Ps. 4,530,614 and Ps. 7,623,880, respectively, were recognized as revenue. C. Practical expedients i. Significant financial component, less than one year PEMEX does not need to adjust the amount committed in consideration for goods and services to account for the effects of a significant financing component, since the transfer and the time of payment of a good or service committed to the customer is less than one year. ii. Practical expedient PEMEX applied the practical expedient, so disclosure about remaining performance obligations that conclude in less than one year is not needed. When PEMEX is entitled to consideration for an amount that directly corresponds to the value of the performance that PEMEX has completed, it may recognize an income from ordinary activities for the amount to which it has the right to invoice. D. Notable External Events i. COVID-19 pandemic impacts In 2020, the effects of the COVID-19 pandemic led to a worldwide economic slowdown, and a resulting decrease in global demand for crude oil and derivatives. In addition, on March 6, 2020, the Organization of the Petroleum Exporting Countries (“OPEC”), led by Saudi Arabia, Russia and other groups of petroleum producers, did not come to an agreement to reduce crude oil production in order to support crude oil prices, which resulted in a significant drop in global crude oil prices. On April 20, 2020, the Mexican crude oil export price reached an unprecedented low of negative U.S.$ 2.37 per barrel. This drastic drop in price was due to low oil demand as a result of COVID-19 and the lack of oil storage. Principally as a result of these factors, PEMEX's total sales decreased by 32% during 2020 as compared to 2019. During 2021, 2022 and as of the date of these Consolidated Financial Statements, all of PEMEX’s operations have continued without interruptions related to COVID-19. During 2021 and 2022, international crude oil and natural gas prices have remained volatile but largely recovered, primarily due to geopolitical events unrelated to COVID-19, reducing possible adverse effects on PEMEX’s results of operation and financial situation. The extent to which COVID-19 or other health pandemics or epidemics may continue to impact Mexico, the Mexican economy and the global economy and, in turn, PEMEX's business, results of operations and financial condition is highly uncertain and will depend on numerous evolving factors that cannot be predicted. ii. Russian activities in Ukraine and the related destabilization of the world energy markets As a result of the ongoing military conflict involving Russia and Ukraine, the prices of oil and natural gas remain extremely volatile. PEMEX’s revenues and profitability are heavily dependent on the prices it receives from sales of oil and natural gas. Oil prices are particularly sensitive to actual and perceived threats to global political stability and to changes in production from OPEC and OPEC+ member states and other oil-producing nations. Destabilization of global oil and gas prices could reduce PEMEX’s sales and adversely affect PEMEX’s results and profitability. Increases in oil and gas prices may not persist and could be followed by price decreases based on factors beyond our control, including geopolitical event. During 2022, the price of the Mexican crude oil export mix increased by U.S.$22.56 or 34.3%, from U.S.$65.85 per barrel in 2021 to U.S.$88.41 per barrel in 2022, which was reflected in the increase in the value of PEMEX’s revenues. Total revenues increased by 59.4% or Ps. 887,759,689 in 2022, from Ps. 1,495,628,620 in 2021 to Ps. 2,383,388,309 in 2022, mainly due to increases in the sales prices of gasoline, diesel, fuel oil, jet fuel, natural gas and natural gas liquids. E . The Automotive Incentive On March 4, 2022, the Mexican Government published a decree in the Official Gazette of the Federation establishing a tax incentive pursuant to which PEMEX can recover the difference between the international reference price of gasoline and the price at which the gasoline is traded in the domestic market, effective until December 31, 2024. For the twelve-month period ended December 31, 2022, this complementary incentive amounted Ps. 111,863,956, which is included as a separate line item in total sales in the Statement of Comprehensive Income (see Note 3-S).

(2,013,915,861) Debt is valued and registered at amortized cost and the fair value of debt is estimated using quotes from major market sources which are then adjusted internally using standard market pricing models. As a result of relevant assumptions, the estimated fair value does not necessarily represent the actual terms at which existing transactions could be liquidated or unwound. The information related to “Cash and cash equivalents”, “Customers and other accounts receivable”, “Investments in joint ventures and associates”, “Promissory notes issue, government bonds, long-term notes receivable and other assets”, “Debt”, “Leases” and “Derivative financial instruments” is described in the following notes, respectively: • Note 9, Cash and cash equivalents. • Note 10, Customers and other financing and non-financing accounts receivable. • Note 12, Investments in joint ventures and associates. • Note 15, Promissory notes issue, government bonds, long-term notes receivable, government bonds and other assets. • Note 16, Debt. • Note 17, Leases. • Note 18, Derivative financial instruments. B. Fair value hierarchy PEMEX values the fair value of its financial instruments under standard methodologies commonly applied in the financial markets. PEMEX’s related assumptions and inputs therefore fall under the three Levels of the fair value hierarchy for market participant assumptions, as described below. The fair values determined by Level 1 inputs utilize quoted prices in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs are based on quoted prices for similar assets or liabilities in active markets, and inputs other than quoted prices that are observed for assets or liabilities. Level 3 inputs are unobservable inputs for the assets or liabilities, and include situations where there is little, if any, market activity for the assets or liabilities. Management uses appropriate valuation techniques based on the available inputs to measure the fair values of PEMEX’s applicable financial assets and financial liabilities.

(211,363) Methodology to determine the estimation of the impairment of the accounts receivable PEMEX allocates each exposure to a credit risk grade based on data that is determined to be predictive of the risk of loss (including but not limited to, audited financial statements, management accounts and cash flow projections and available information about customers) and applying experienced credit judgment. Credit risk grades are defined using qualitative and quantitative factors that are indicative of the risk of default. Exposures within each credit risk grade are segmented by each Subsidiary Entity and its commercial business lines, so the expected credit loss rate is calculated for each segment based on actual credit loss experienced over the past two years. These rates are multiplied by scale factors to reflect differences between the economic conditions during the period over which historical data has been collected, current conditions and PEMEX’s view of economic conditions over the expected lives of the receivables. As of December 31, 2022, the expected percentage of credit loss for accounts receivable for each Subsidiary Entity and Subsidiary Company was: 7.36% for Pemex Industrial Transformation, 3.87% for Pemex Corporate, 0.88% for Pemex Logistics, 0.16% for PMI CIM and 0.13% for PMI TRD. As of December 31, 2021, the expected percentage of credit loss for accounts receivable for each Subsidiary Entity and Subsidiary Company was: 5.09% for Pemex Industrial Transformation, 2.99% for Pemex Corporate, 0.58% for Pemex Logistics, 0.01% for PMI CIM and 0.80% for PMI TRD. The amount of (impairment) of domestic and export customers recognized in the statement of comprehensive income for 2022, 2021 and 2020 was Ps. (2,035,004), Ps. (2,349,095) and Ps.

Additional information about the significant investments in joint ventures and associates is presented below: Joint venture • Deer Park . On March 31, 1993, PMI NASA acquired 49.995% of the Deer Park Refinery. In its capacity as general partner of DPRLP, Shell was responsible for the operation and management of the Deer Park Refinery (installed capacity of approximately 340,000 barrels per day of crude oil). Management decisions were made jointly with respect to investment in or disposal of assets, distribution of dividends, indebtedness and equity operations. In accordance with the investment contract and the operation of the agreement, the participants had the rights to the net assets in the proportion of their participation. This joint venture was recorded under the equity method. The investment in Deer Park as of December 31, 2021 was Ps. 6,703,324, which represented PMI NASA’s 49.995% interest in Deer Park (see subsection A.). COVID-19 negatively impacted the energy industry due to mobility restrictions and stoppages in several industries. For the Deer Park Refinery these impacts were observed in the reduction in refining margins due to lower demand in fuels. Therefore, at the beginning of 2021, Deer Park’s partners decided to support the refinery financially, given problems with liquidity toward the end of 2020. The support from Deer Park’s partners allowed us to continue the operation of the refinery. During 2021, there were three material impacts on the results: a. Low refining margins due to lower international demand as a result of the COVID-19 pandemic. b. Winter Storm Suspension. In February 2021, industries within the Texas area were affected by heavy snowfall. For the Deer Park Refinery, this scenario resulted in a total emergency stoppage and the activities resumed by the last week of March 2021. However, repair activities were required and were completed in November 2021. c. As established under the Renewable Fuel Standard Program of the Environmental Protection Agency of the United States of America, we are required to blend renewable products for transportation fuels, which led to an increase in renewable blending cost obligations from a higher price of “ Renewal Identification Numbers”. Acquisition of the joint venture See accounting policy in Note 3-A(i) (Business combinations) and (v) (Interests in equity-accounted investees) of PEMEX’s annual consolidated financial statements as of and for the year ended December 31, 2022. As a result of the above mentioned, indications of impairment were identified, and at the end of 2021, impairment tests were carried out on the amount of the investment recognized in Deer Park, and the result was the recognition of a total impairment in the book value of the investment as of December 31, 2021 of Ps. 6,703,324, which is presented as a separate line item in the statement of comprehensive income. In this observable transaction the value of the debt was agreed up to U.S.$1,192,000 as the fair value of the 100% of the interest in Deer Park, i.e., U.S.$596,000, equivalent to 50.005% of the interest. On January 20, 2022, PMI SUS acquired the remaining 50.005% of participation and voting interest in Deer Park through a purchase agreement with Shell. Through this operation, PEMEX indirectly acquired control over Deer Park. As a result of the acquisition, this company is now consolidated in PEMEX’s financial statements. Beginning January 20, 2022, DPRLP’s business model changed from a company that obtained revenues from services for processing crude oil to a company that buys and processes crude oil and sells gasolines and distillates. Deer Park is a limited partnership under the laws of Delaware, with operations in Deer Park, Texas. The purpose of the acquisition is to strengthen and increase the refining capacity under PEMEX’s control. PEMEX has begun shipping products to Mexico from the refinery to strengthen the fuels supply. Prior to the acquisition, the participation in Deer Park was recognized as a joint venture. As a result, the participation was recognized in PEMEX’s consolidated financial statements using the equity method. On November 3, 2021, the Board of Directors authorized PEMEX’s capitalization of HHS and HPE up to the amount received from the Fondo Nacional de Infraestructura (National Infrastructure Fund or “FONADIN”) as a non-recoverable contribution to enable HHS and HPE, in turn, to capitalize PMI NASA and PMI SUS. These capitalizations were used to meet financial commitments arising out of the acquisition of Shell’s interest in Deer Park. During January 2022, the amount received and recorded from the FONADIN totaled Ps. 23,000,000 (U.S.$1,127,285). In addition, PEMEX entered into a borrowing of Ps. 8,974,406 (U.S.$436,000) due in one year. In recognition of this transaction, PEMEX is applying the purchase method in accordance with International Financial Reporting Standard (IFRS) 3 “Business Combinations”, accounting for the transaction as a business combination achieved in stages. The acquiree company included in the identifiable assets at the date of acquisition of DPRLP are inputs (mainly Properties, Plant and Equipment and inventories), production processes and workforce. PEMEX has determined that together the acquired inputs and processes significantly contribute to the ability to generate revenue. PEMEX has concluded that the acquired set is a business. Consideration transferred PEMEX’s purchase of control of Deer Park, through the 50.005% interest owned by Shell, included the following: Cash paid to Shell Ps. 8,597,743 U.S.$ 421,396 Payment of debt to third parties 18,289,066 896,391 Payment of DPRLP’s debt to company partners 3,496,054 171,350 Total consideration paid in cash Ps. 30,382,863 U.S.$ 1,489,137 Settlement of pre-existing relationship 6,663,803 326,609 Total consideration paid in cash and settlement of pre-existing relationship Ps. 37,046,666 U.S.$ 1,815,746 The settlement of the pre-existing relationship includes the payment of 100% of PMI NASA’s Partners Loan (Ps. 1,227,383 or U.S.$60,157 with cash and Ps. 5,436,420 or U.S.$266,452 with equity) which Deer Park used for operative purposes, and which consisted of a principal of Ps. 6,630,975 (U.S.$325,000) and interest of Ps. 32,828 (U.S.$1,609). With this settlement, the account receivable registered on PMI NASA’s books was capitalized. As the book value of this item was equal to its fair value and there were no cancellation clauses, no effects were recognized in the profit or loss of the period. Acquisition-related costs Acquisition-related costs for the 50.005% interest in Deer Park totaled Ps. 145,937 (U.S.$7,091) recognized in the administrative expenses line item in the profit or loss for the applicable period. Identifiable assets acquired and liabilities assumed. The following table summarizes the fair value of the identifiable assets acquired, including the recognized value of the PEMEX interest prior to the purchase. Cash and cash equivalents Ps. 1,597,759 U.S.$ 78,310 Inventories 6,918,473 339,091 Other current assets 131,661 6,453 Total current Assets Ps. 8,647,893 U.S.$ 423,854 Property, Plant and Equipment 29,669,961 1,454,196 Total identifiable net assets acquired Ps. 38,317,854 U.S.$ 1,878,050 PEMEX carried out the valuation of the fair value of the business acquired under the market approach since it has information on an observable transaction between independent parties, is duly informed and is in a free competition market. At the acquisition date, considering the amount of the value of the net assets and the consideration transferred, a gain at a bargain purchase was determined as follows: Total consideration transferred Ps. 37,046,666 U.S.$ 1,815,746 Fair value of the identifiable net assets acquired (38,317,854) (1,878,050) Gain on bargain purchase Ps. (1,271,188) U.S.$ (62,304) There was not any gain or loss in the previously held interest because the book value and the fair value of these items was zero at the acquisition date. The technique used for the measuring of the fair value of the previous held interest was the adjusted book value method. The gain on bargain purchase was recognized in other income line item in the profit or loss of the period. The gain of U.S.$62,304 (Ps. 1,271,188) was due to closing adjustments consisting of Shell’s assumption of DPRLP’s accrued expenses and taxes and the pro-rated cash. From the acquisition date to December 31, 2022, DPRLP contributed Ps. 238,940,945 to PEMEX’s total revenues and Ps. 20,905,292, to PEMEX’s total income for the period. As of December 31, 2022, PEMEX recognized Ps. (10,383,296) of currency translation effects from the investment in DPRLP into other income, as a result of derecognizing the equity method.

(3) On January 20, 2022, PEMEX acquired assets with a cost of Ps. 29,669,961, consisting mainly of plants. This amount includes assets acquired through a business combination (see Note 12). A. As of December 31, 2022, 2021 and 2020, the financing cost identified with fixed assets in the construction or installation stage, capitalized as part of the value of such fixed assets, was Ps. 4,580,836, Ps. 3,106,007 and Ps. 3,893,248, respectively. Financing cost rates during 2022, 2021 and 2020 were 5.40% to 7.80%, 6.10% to 7.05% and 5.75% to 7.08%, respectively. B. The combined depreciation of fixed assets and amortization of wells for the fiscal years ended December 31, 2022, 2021 and 2020, recognized in operating costs and expenses, was Ps. 139,771,815, Ps. 133,431,365 and Ps. 129,631,820, respectively. These figures include Ps. 113,656,994, Ps. 108,509,633 and Ps.101,339,417 for oil and gas production assets and costs related to plugging and abandonment of wells for the years ended December 31, 2022, 2021 and 2020 of Ps. 224,327, Ps. 143,779 and Ps. 2,731,317, respectively. C. As of December 31, 2022 and 2021, provisions relating to future plugging of wells costs amounted to Ps. 66,699,388 and Ps. 70,144,756, respectively, and are presented in the “Provisions for plugging of wells” (see Note 20). D. As of December 31, 2022, 2021 and 2020, acquisitions of property, plant and equipment include transfers from wells unassigned to a reserve for Ps. 10,630,314, Ps. 15,608,296 and Ps. 6,229,356, respectively (see Note 14). E. As of December 31, 2022, 2021 and 2020, the translation effect of property, plant and equipment items from a different currency than the presentation currency was Ps. (14,982,766), Ps. 2,477,528 and Ps. 490,203, respectively, which was mainly plant. F. As of December 31, 2022, 2021 and 2020, PEMEX recognized a net impairment of Ps. (83,538,021), Ps. (1,210,595) and Ps.

(60,438,070) 34,562,831 35,031,541 As of December 31, 2022, Pemex Exploration and Production recognized a net impairment of Ps. (60,438,070) mainly due to: (i) a decrease in production profiles volume in the barrel of crude oil equivalent generating a negative effect of Ps. 258,263,054, of which Ps. 160,892,540 are from the Cantarell CGU, Aceite Terciario del Golfo (“ATG”), Ixtal Manik, Antonio J. Bermúdez and Chuc CGUs; and (ii) the negative effect due to an exchange rate of Ps. 17,568,491, from Ps. 20.5835 = U.S.$1.00 as of December 31, 2021, to Ps. 19.4143 = U.S.$1.00 as of December 31, 2022. These effects were partially offset by (i) an increase in crude oil prices, generating a positive effect of Ps. 157,896,123 mainly Burgos, Ogarrio Magallanes and Crudo Ligero Marino CGUs; (ii) an increase in the discount rate of Ps. 52,553,703, from 6.89% in 2021 to 9.31% in 2022, due to the increase in the debt component in the Weighted Average Cost of Capital ("WAAC") derived from the rise in global interest rates, which impacted PEMEX's benchmark rates that oil and gas industry uses to determine these discount rates, mainly in the Cantarell CGU due to the 30.5% reduction in proved reserves as of January 31, 2023, from 683.83 MMBPCE as of December 31, 2021 to 474.96 MMBPCE as of December 31, 2022; and (iii) a positive tax effect of Ps. 4,943,649, due to lower income in proved reserves as of January 1, 2023 mainly in the Cantarell, ATG and Ixtal Maniak CGUs. As of December 31, 2021, Pemex Exploration and Production recognized a net reversal of impairment of Ps. 34,562,831 mainly due to: (i) an increase in crude oil prices, generating a positive effect of Ps. 143,823,094 mainly in ATG, Chuc, Crudo Ligero Marino and Ixtal Manik CGUs; (ii) the positive effect due to an exchange rate of Ps. 13,361,080, from Ps. 19.9478 = U.S.$1.00 as of December 31, 2020, to Ps. 20.5835 = U.S.$1.00 as of December 31, 2021; and (iii) a slight positive effect in the discount rate of Ps. 624,875, or in percentage terms, from 6.23% in 2020 to 6.89% in 2021. These effects were partially offset by (i) a decrease in production profiles volume in the barrel of crude oil equivalent of Ps. 34,944,968 and higher transportation and distribution costs of Ps. 67,992,525 mainly in Cantarell, Burgos, Antonio J. Bermúdez and Macuspana, CGUs; (ii) an increase in proven reserves in the new Ixachi, Quequi, Xikin, Jaatsul, Cheek, Uchbal, TetL, Teekit, Suuk, Pokche and Mulach fields; (iii) a negative tax effect of Ps. 18,119,284, due to higher income as a result of an increase in hydrocarbon prices, exchange rate and an increase in the discount rate with respect to December 31, 2020 mainly in ATG, Chuc, Crudo Ligero Marino and Tsimin Xux CGUs; and (iv) an impairment of Ps. 2,189,440 in Exploration and Extraction Contracts for Misión and Ébano CGUs. As of December 31, 2020, Pemex Exploration and Production recognized a net reversal of impairment of Ps. 35,031,541, mainly due to: (i) an increase in crude oil prices, generating a positive effect of Ps. 50,763,557 mainly in the Cantarell and ATG CGUs (ii) an increase in the volume of barrels of crude oil equivalent, generating an effect of Ps. 33,784,306 mainly in the ATG, Burgos and Crudo Ligero Marino CGUs. Additionally, there were increases in proven reserves in new fields, including Ixachi, Xikin, Jaatsul, Cheek, Uchbal, Tetl, Teekit, Suuk, Pokche and Mulach; (iii) the positive effect due to an exchange rate of Ps. 21,067,337, mainly in Cantarell, ATG and Burgos CGUs, from Ps. 18.8452 = U.S.$1.00 as of December 31, 2019 to Ps. 19.9478 = U.S.$1.00 as of December 31, 2020; and (iv) an increase in taxes of Ps. 3,844,410 was recognized due to a lower income in the production and price profiles as compared to December 31, 2019, impacting Antonio J. Bermúdez, Chuc and Tsimin Xux CGUs, among others. These effects were partially offset by an increase in the discount rate of Ps. 74,428,069, or in percentage terms, from 6.18% in 2019 to 6.23% in 2020, which motivated the CGUs with higher revenues, sales volume, price and exchange rates to recognize this effect. The CGUs of Pemex Exploration and Production are investment projects in productive fields with hydrocarbon reserves associated with proved reserves. These productive hydrocarbon fields contain varying degrees of heating power consisting of a set of wells and are supported by fixed assets associated directly with production, such as pipelines, production facilities, offshore platforms, specialized equipment and machinery. Each project represents the smallest unit which can concentrate the core revenues, with clear costs and expenses that enable future cash flows (value in use) to be determined. Pemex Exploration and Production determines the recoverable amount of fixed assets based on the long-term estimated prices for Pemex Exploration and Production’s proved reserves. The recoverable amount on each asset is the value in use. To determine the value in use of long-lived assets associated to hydrocarbon extraction, the net present value of reserves is determined based on the following assumptions: 2022 2021 2020 Average crude oil price 59.37 U.S.$/bl 56.60 U.S.$/bl 52.96 U.S.$/bl Average gas price 4.98 U.S.$/mpc 4.66 U.S.$/mpc 5.21 U.S.$/mpc Average condensates price 64.95 U.S.$/bl 65.50 U.S.$/bl 61.09 U.S.$/bl After-tax discount rate 9.31% annual 6.89% annual 6.23% annual Pre-tax discount rate 14.27% annual 10.68% annual 9.72% annual For 2022, 2021 and 2020 the total forecast production, calculated with a horizon of 25 years, was 7,078 Billion barrels per day (Bbd), 7,341 Bbd and 6,731 Bbd per day of crude oil equivalent, respectively. Pemex Exploration and Production, in compliance with practices observed in the industry, estimates the recovery value of an asset by determining its value in use, based on cash flows associated with proved reserves after taxes and using a discount rate, also after taxes. Cash flows related to plugging wells provision costs are excluded in this computation of discounted cash flows. As of December 31, 2022, 2021 and 2020, values in use for CGU with impairment or reversal of impairment are: 2022 2021 2020 Chuc Ps. 58,826,338 86,217,289 35,037,408 Aceite Terciario del Golfo 44,910,967 75,544,451 38,617,385 Tsimin Xux 42,487,962 29,336,464 21,703,642 Ogarrio Magallanes 29,222,531 25,089,823 — Crudo Ligero Marino 27,993,723 34,424,670 11,455,311 Burgos 13,254,788 4,403,791 16,003,831 Ixtal - Manik 10,377,668 23,071,621 10,361,747 Antonio J.

(71,761,571), respectively, shown by CGUs as follows: 2022 2021 2020 Minatitlán Refinery (17,502,044) (4,678,358) (37,432,704) Morelos Petrochemical Complex (7,512,584) 365,522 (2,350,704) Cangrejera Petrochemical Complex (6,419,084) (1,115) — Salamanca Refinery (5,819,013) (2,187,781) (5,386,525) Poza Rica Gas Processor Complex (3,656,338) — — Arenque Gas Processor Complex (199,943) — — Salina Cruz Refinery (101,943) (3,263,118) — Cadereyta Refinery (68,460) (2,195,115) (2,083,755) Tula Refinery 9,757,714 (6,446,357) (2,820,750) Madero Refinery 5,244,262 (13,216,073) (18,412,688) Cosoleacaque Petrochemical Complex 630,486 (726,631) — Pajaritos Petrochemical Complex 31,596 195,834 (1,484,489) Nuevo Pemex Gas Processor Complex — — (1,080,831) Ciudad Pemex Gas Processor Complex — — (709,125) Total Ps. (25,615,351) (32,153,192) (71,761,571) As of December 31, 2022, the net impairment of Ps. (25,615,351) was mainly due to: (i) the negative effect due to an exchange rate, from Ps. 20.5835 = U.S.$1.00 as of December 31, 2021, to Ps. 19.4143 = U.S.$1.00 as of December 31, 2022, and (ii) a negative effect in the discount rate, from 9.45% in 2021 to 14.16% in 2022; and (iii) a projected decrease in revenues. As of December 31, 2021, the net impairment of Ps. (32,153,192) was mainly the result of the following factors: (i) the inability to achieve the projected production rate due to operational issues; (ii) the Ultra-Low Sulfur Gasoline (ULSG) and Ultra-Low Sulfur Diesel (ULSD) projects have not received any resources for their continuation and no provision is made for the continuation of these works within the approved budget for 2022; and (iii) the total impairment in the Madero Refinery due to high operating costs and expenses. These effects were partially offset by (i) a projected increase in revenues due to the increase in sales prices for secondary petrochemical CGUs; (ii) an increase in the exchange rate of the peso against the U.S. dollar, from a peso/U.S. dollar exchange rate of Ps. 19.9487 = U.S.$1.00 as of December 31, 2020, to Ps. 20.5835 = U.S.$1.00 as of December 31, 2021; and (iii) a decrease in the discount rate from 10.83% in 2020 to 9.45% in 2021. As of December 31, 2020, the impairment of Ps. (71,761,571) was mainly due to (i) lower production levels, mainly at the Madero, Minatitlan and Tula Refineries due to a lower crude oil processing rate than previously projected; (ii) decrease in the price of products; (iii) a decrease in the discount rate of CGUs of refined products and gas by 0.64% and 0.46%, respectively, and increase in petrochemicals by 1.15% and ethylene by 0.26%; and (iv) the depreciation of the peso against the U.S. dollar, from a peso/U.S. dollar exchange rate of Ps. 18.8452 = U.S.$1.00 as of December 31, 2019 to Ps. 19.9487 = U.S.$1.00 as of December 31, 2020, which are used as cash flows when U.S. dollars are taken as reference. To determine the value in use of long-lived assets associated with the CGUs of Pemex Industrial Transformation, the net present value of cash flows was determined based on the following assumptions: As of December 31, 2022 2021 2020 2022 2021 2020 2022 2021 2020 2022 2021 2020 2022 2021 Refining Gas Petrochemicals Ethylene Fertilizers Average crude oil Price (U.S.$) 68.79 60.4 48.89 N.A.

N.A. = Not applicable CGUs in Pemex Industrial Transformation are processing centers grouped according to their types of processes as refineries, gas complex processors, and petrochemical centers. These centers produce various finished products for direct sale to customers or intermediate products that can be processed in another of its CGUs or by a third party. Each processing center of Pemex Industrial Transformation represents the smallest unit that has distinguishable revenues, with clear costs and expenses that enable future cash flows (value in use) to be determined. Cash flow determinations are made based on PEMEX’s business plans, operating financial programs, forecasts of future prices of products related to the processes of the CGUs, budget programs and various statistical models that consider historical information of processes and the capacity of various processing centers. The recoverable amount of assets is based on each asset’s value in use. The value in use for each asset is calculated based on discounted cash flows, taking into consideration the volumes to be produced and sales to be carried out. As of December 31, 2022, 2021 and 2020, the value in use for the impairment of fixed assets was as follows: 2022 2021 2020 Salina Cruz Refinery Ps. 49,725,087 31,909,325 30,422,588 Tula Refinery 48,695,398 39,815,742 34,829,922 Cadereyta Refinery 48,191,707 39,432,148 40,793,541 Nuevo Pemex Gas Processor Complex 31,708,026 — — Salamanca Refinery 17,799,786 51,998,803 44,777,784 Madero Refinery 10,279,749 — 6,799,072 Minatitlán Refinery 4,061,210 20,545,810 18,819,247 Cosoleacaque Petrochemical Complex 1,974,484 625,255 — Arenque Gas Processor Complex 105,610 — — Cangrejera Ethylene Processor Complex — — 11,493,567 Morelos Ethylene Processor Complex — 7,903,064 9,396,765 Total Ps. 212,541,057 192,230,147 197,332,486 Cash-Generating Units of Pemex Logistics As of December 31, 2022, 2021 and 2020, Pemex Logistics recognized a net reversal of impairment of Ps. 2,121,045, an impairment of Ps.

Disclosure Of Notes Receivable Government Bonds And Other Long Term Assets [Abstract]
Government Bonds, Long-Term Notes Receivable And Other Assets	GOVERNMENT BONDS, LONG-TERM NOTES RECEIVABLE AND OTHER ASSETS A. Promissory notes On August 5, 2016, Petróleos Mexicanos received promissory notes issued by the Mexican Government as part of the Mexican Government’s assumption of a portion of the payment liabilities related to Petróleos Mexicanos and Subsidiary Entities’ pensions and retirement plans. On November 19, 2020, Petróleos Mexicanos and the SHCP agreed to exchange 16 promissory notes in favor of Petróleos Mexicanos for 18 series of Mexican Government local bonds (the “Government Bonds”). The resources from the Government Bonds will be exclusively transferred to the FOLAPE for the payments related to its pension and retirement plan obligations. The roll-forward related to the promissory notes as of December 31, 2020 is as follows: For the year ended 2020 (i) Balance at the beginning of the year Ps. 126,534,822 Collected promissory notes (4,102,622) Accrued interests 7,097,040 Interests received from promissory notes (881,048) Reversal of (impairment) of the promissory notes 8,000 Exchange from promissory notes to Bonds (128,656,192) Balance at the end of the period Ps. — (i) Until November 19, 2020. B. Government bonds As of December 31, 2022 and 2021, the balance of Government Bonds (see Note 15-A), includes Government Bonds valued at amortized cost as follows: 2022 2021 Government bonds (1) Ps. 110,179,517 Ps. 110,855,356 Less: current portion of Government Bonds, net of expected credit losses 46,526,257 1,253,451 Total long-term notes receivable Ps. 63,653,260 Ps. 109,601,905 (1) As of December 31, 2022 and 2021, includes an expected credit loss of Ps. 9,717 and Ps. 13,038, respectively. As of November 19, 2020, the value of the Government Bonds was Ps. 128,786,611, and the liability was Ps. 95,597,610. On November 20, 2020, Petróleos Mexicanos monetized the whole of the Government Bonds by entering into a three-year financial arrangement to partially raise an equivalent of Ps. 95,597,610 at an annual rate of 8.56275%, maturing November 24, 2023. Petróleos Mexicanos retains the risks, benefits and economic rights of the Government Bonds, which were delivered to a financial institution. Petróleos Mexicanos will continue to collect coupon and principal payments from the securities throughout the term of the transaction. Therefore, Petróleos Mexicanos recognizes these Government Bonds as restricted assets and recognizes short-term debt for the monetization.

Derivative Financial Instrument

Disclosure of detailed information about financial instruments [abstract]
Derivative Financial Instruments	DERIVATIVE FINANCIAL INSTRUMENTS PEMEX faces market risk caused by the volatility of hydrocarbon prices, exchange rates and interest rates, credit risk associated with investments and financial derivatives, as well as liquidity risk. In order to monitor and manage these risks, PEMEX has approved general provisions relating to financial risk management, which are comprised of policies and guidelines that promote an integrated framework for risk management, regulate the use of Derivative Financial Instruments (DFIs), and guide the development of risk mitigation strategies. This regulatory framework establishes that DFIs should be used only for the purpose of mitigating financial risk. The use of DFIs for any other purpose must be approved in accordance with PEMEX’s current internal regulation. PEMEX has a Financial Risk Working Group (FRWG) which is a specialized working group with decision-making authority on financial risk exposure, financial risk mitigation schemes, and DFIs trading of Petróleos Mexicanos, the subsidiary entities, and where applicable, the subsidiary companies. Approved DFIs are mainly traded on the Over-the-Counter (OTC) market; however, exchange traded instruments may also be used. In the case of PMI Trading, DFIs are traded on CME-Clearport. The different types of DFIs that PEMEX trades are described below in the subsections corresponding to each risk type and as related to the applicable trading markets. One of PEMEX’s policies is to contribute to minimizing the impact that unfavorable changes in financial risk factors have on its financial results by promoting an adequate balance between incoming cash flows from operations and outgoing cash flows related to its liabilities. As part of the regulatory framework for financial risk management, PEMEX has established the eligible counterparties with which it may trade DFIs and other financial instruments. In addition, certain PMI Subsidiaries have implemented a regulatory framework for risk management with respect to its activities, which consists of policies, guidelines and procedures to manage the market risk associated with its commodity trading activities in accordance with industry best practices, such as: 1) the use of DFIs for financial risk mitigation purposes; 2) the segregation of duties; 3) valuation and monitoring mechanisms, such as the generation of a daily portfolio risk report, value at risk (“VaR”) computation; and 4) VaR limits, both at a global and business unit level and the implementation of stop loss mechanisms. Given that PEMEX’s outstanding DFIs have been entered into for risk mitigation purposes, particularly with economic hedging purposes, there is no need to establish and monitor market risk limits. For those portfolios with an open market risk exposure, PEMEX’s financial risk management regulatory framework establishes the implementation and monitoring of market risk metrics and limits (such as VaR, among others). PEMEX has also established credit guidelines for DFIs that Pemex Industrial Transformation offers to its domestic customers, which include the use of guarantees and credit lines. For exchange traded DFIs PEMEX trades under the margin requirements of the corresponding exchange market, and therefore does not have internal policies for these DFIs. DFIs held with financial counterparties do not require collateral exchange clauses. Notwithstanding, PEMEX’s regulatory framework promotes credit risk mitigation strategies such as collateral exchange. PEMEX does not have an independent third party to verify compliance with these internal standards; however, PEMEX has internal control procedures that certify compliance with existing policies and guidelines. A. Risk Management I. Market Risk i. Interest rate risk PEMEX is exposed to fluctuations in floating interest rate liabilities. PEMEX is exposed to U.S. dollar LIBOR, U.S. dollar SOFR and to Mexican peso TIIE. As of December 31, 2022, 18.7% of PEMEX’s total net debt outstanding (including DFIs) consisted of floating rate debt. Occasionally, for strategic reasons or in order to offset the expected inflows and outflows, PEMEX has entered into interest rate swaps and options. Through the swap agreements, PEMEX acquires the obligation to make payments based on a fixed interest rate in exchange for receiving payments referenced to a floating interest rate. On the other hand, under the option agreements, PEMEX acquires protection against possible raises in the floating interest rates of some of its liabilities. As of December 31, 2022, Petróleos Mexicanos was a party to four interest rate swap agreements denominated in U.S. dollars for an aggregate notional amount of U.S.$511,250 at a weighted average fixed interest rate of 2.34% and a weighted average term of 2.5 years. Similarly, in order to eliminate the volatility associated with variable interest rates of long-term financing operations, PMI NASA has also executed two interest rate swap agreements denominated in U.S. dollars for an aggregate notional amount of U.S. $1,378, at a weighted average fixed interest rate of 3.80% and a weighted average term of 0.17 years. Moreover, PEMEX invests in pesos and U.S. dollars in compliance with applicable internal regulations, through portfolios that have different purposes that seek an adequate return subject to risk parameters that reduce the probability of capital losses. The objective of the investments made through these portfolios is to meet PEMEX’s obligations payable in pesos and U.S. dollars. The investments made through PEMEX’s portfolios are exposed to domestic and international interest rate risk and credit spread risk derived from government and corporate securities, and inflation risk arising from the relationship between UDIs and pesos. However, these risks are mitigated by established limits on exposure to market risk. IBOR reference rates transition As a result of the decision made by the Financial Stability Board (FSB), the Interbank Offered Rates (IBORs), such as the LIBOR in dollars (over-night “O/N”, one week “1W”, two months “2M” and twelve months “12M”) or the EURIBOR in Euros, ceased being published in 2022 and were required to be replaced by alternative reference rates, based on risk-free rates obtained from market operations. The discontinuation of the publication of these rates was originally scheduled for December 2021. Nevertheless, on November 2020, the ICE Benchmark Administration Limited (known as “ICE”) announced an extension until June 2023 for the publication of the most common LIBOR rates in dollars, (one month “1M”, three months “3M”, six months “6M” and twelve months "12M"). Therefore, PEMEX has identified and is reviewing contracts expiring after the applicable discontinuation dates, that could be impacted by the change in the aforementioned rates. As of December 31, 2022, PEMEX has a reduced number of financial instruments referenced to floating rates in U.S. dollars with maturity and interest rate fixation after June 2023. This portfolio of financial instruments is composed of debt instruments and DFIs as shown below: Reference Rate *Notional Amount Debt LIBOR 1M U.S.$ 471,780 LIBOR 3M U.S.$ 343,710 LIBOR 6M U.S.$ 787,068 DFI LIBOR 1M U.S.$ 2,500,000 LIBOR 3M U.S.$ 156,250 LIBOR 6M U.S.$ 243,750 * Note: Notional amounts with maturity after June 30, 2023. Petróleos Mexicanos has a financial instrument denominated in Euros with the EURIBOR 3M as a reference rate. This reference will continue to be published, by agreement of the European financial authorities, so the current contract does not require any amendment. In the event that TIIE ceases to be published, the portfolio of financial instruments referenced to these floating rates is composed of debt instruments and DFIs as shown below: Reference Rate *Notional Amount Debt TIIE 28D MXN 66,950,939 TIIE 91D MXN 20,392,684 DFI TIIE 28D MXN 31,733,673 * Note: Notional amounts with maturity after December 31, 2022. PEMEX’s portfolio also consists of additional debt instruments and DFIs referenced at fixed rates, which are not listed in the tables above since PEMEX’s fixed rate portfolio will not be impacted by the IBOR transition. Currently, PEMEX has been in constant communication with its counterparties, in order to carry out this transition in the most efficient way possible. In addition, as a result of the transition, PEMEX is working on any amendments to its contracts that may be required and is monitoring the evolution of the IBORs transition in the market, in order to anticipate any negative impact that these changes may have. Derived from the transition to the alternative reference rates based on risk-free rates (RFR), PEMEX has adopted the policy of not entering into new DFIs referenced to IBOR rates. Additionally, some of the discount curves that PEMEX uses to obtain the fair value of its DFIs already include on their construction instruments of the corresponding currency referenced to the new RFR. Additionally, as a result of the policy of not entering into new financing operations at floating rates linked to IBOR, during 2021 and 2022, PEMEX contracted financing operations in U.S. dollars at floating rates linked to the new RFR rates. The credit agreements of PMI Trading include flexible provisions that help realize an orderly transition to an alternative rate in the event that the LIBOR rates ceased to be published. Currently, PMI Trading’s negotiations to adopt the new benchmark rate have concluded and PMI Trading has agreed to the new benchmark of Secured Overnight Funding Rate (SOFR) starting on July 1, 2023, or on any previous date, once LIBOR ceases to be available. ii. Exchange rate risk Most of PEMEX’s revenues are denominated in U.S. dollars, a significant amount of which is derived from exports of crude oil and petroleum products, which are priced and payable in U.S. dollars. Additionally, PEMEX’s revenues from domestic sales of gasoline and diesel net of IEPS Tax, tax duties, incentives, and other related taxes, as well as domestic sales of natural gas and its byproducts, LPG and petrochemicals, are referenced to international U.S. dollar-denominated prices. PEMEX’s expenses related to hydrocarbon duties are calculated based on international U.S. dollar-denominated prices and the cost of hydrocarbon imports that PEMEX acquires for resale in Mexico or use in its facilities are indexed to international U.S. dollar-denominated prices. By contrast, PEMEX’s capital expenditure and operating expenses are established in pesos. As a result of this cash flow structure, the depreciation of the peso against the U.S. dollar increases PEMEX’s financial balance. The appreciation of the peso relative to the U.S. dollar has the opposite effect. PEMEX manages this risk without the need for hedging instruments because the impact on PEMEX’s revenues of fluctuations in the exchange rate between the U.S. dollar and the peso is offset in whole or in part by its impact on its obligations. PEMEX prioritizes debt issuances denominated in U.S. dollars; nonetheless, this is not always achievable, hence non-U.S. dollar denominated debt issued in international currencies is hedged through DFIs to mitigate their exchange rate exposure, either by swapping it into U.S. dollars or through other derivative structures. The rest of the debt is denominated in pesos or in UDIs, and for the debt denominated in UDIs, it has been converted into pesos through DFIs in order to eliminate the inflationary risk exposure. As a consequence of the above, PEMEX's debt issued in international currencies other than U.S. dollars has exchange rate risk mitigation strategies. PEMEX has selected strategies that further seek to reduce its cost of funding by leaving, in some cases, part of this exchange rate exposure unhedged when assessed as appropriate. The underlying currencies of PEMEX’s DFIs are the euro, Swiss franc, Japanese yen and pounds sterling against the U.S. dollar and UDIs against the peso. As of December 31, 2022, PEMEX did not enter into any DFIs, since no debt in currencies other than U.S. dollars or pesos was issued. During 2021, PEMEX carried out the restructure of five cross-currency swaps, two of them with a recouponing clause. These DFIs hedged the exchange rate exposure of a €1,000,000 debt with maturity in 2026, a €100,000 debt with maturity in 2030 and the 10% of a €1,250,000 debt with maturity in 2027. For this restructure PEMEX entered into, without cost, structures which are composed of a cross-currency swap and the sale of a call option, guaranteeing complete protection up to a certain exchange rate and partial protection above that level. These DFIs maintained the original contractual clauses. Once this restructure had been carried out, 25% of the issue with maturity in 2026 remained hedged with two cross-currency swaps. Additionally, during 2020, PEMEX carried out the restructure of three cross-currency swaps, one of which had a recouponing provision. These DFIs hedged the exchange rate exposure of a €1,250,000 debt with maturity in 2027. For this restructuring, PEMEX entered into, without cost, structures which are composed of a cross-currency swap and the sale of a call option, guaranteeing complete protection up to a certain exchange rate and partial protection above that level. This allowed PEMEX to eliminate the recouponing provision without cost. PEMEX recorded a total foreign exchange gain (loss) of Ps. 129,690,090, Ps. (45,675,050) and Ps. (128,949,304), for the years ended December 31, 2022, 2021 and 2020, respectively; these amounts include the unrealized foreign exchange gain (loss) associated with debt of Ps. 121,255,142, Ps. (40,751,264) and Ps. (122,099,058) for the years ended December 31, 2022, 2021 and 2020, respectively. Unrealized foreign exchange gains and losses do not impact PEMEX’s cash flows. The appreciation of the peso during 2022 caused a total net foreign exchange gain because a significant part of PEMEX’s debt, 85.08% (principal only) as of December 31, 2022, is denominated in a currency other than the Mexican peso. Due to the cash flow structure described above, the depreciation of the peso relative to the U.S. dollar does not affect PEMEX’s ability to meet U.S. dollar-denominated financial obligations and it improves PEMEX’s ability to meet peso-denominated financial obligations. On the other hand, the appreciation of the peso relative to the U.S. dollar may increase PEMEX’s peso-denominated debt service costs on a U.S. dollar basis. Certain of the PMI Subsidiaries face market risks generated by fluctuations in foreign exchange rates. In order to mitigate these risks, the boards of directors of several of these companies have authorized a policy which stipulates that financial assets must be denominated in its functional currency, unless the company owes a duty or expected payment in a currency other than its functional one. Finally, a significant amount of PMI Trading’s income and expenses, including the cost of sales and related sales costs, is derived from the trade of refined products, petrochemicals and gas liquids to PEMEX subsidiaries and third parties, whose prices are determined and are payable in U.S. dollars. PMI Trading’s exposure to foreign currency risk results primarily from the need to fund tax payments denominated in domestic currency, as well as from certain related sales costs denominated in domestic currency. PMI Trading believes it can adequately manage the risk created by the payment of taxes in domestic currency without the need to enter into hedging instruments because the exposure to this risk is marginal relative to the total flows of U.S. dollar. In addition, in the event that a potential foreign exchange risk arises in connection with a commercial transaction, PMI Trading may implement risk mitigation measures by entering into DFIs. iii. Hydrocarbon Price Risk PEMEX periodically assesses its revenues and expenditures structure in order to identify the main market risk factors that PEMEX’s cash flows are exposed to in connection with international hydrocarbon prices. Based on this assessment, PEMEX monitors its exposure to the most significant risk factors and quantifies their impact on PEMEX’s financial balance. PEMEX’s exports and domestic sales are directly or indirectly related to international hydrocarbon prices. Therefore, PEMEX is exposed to fluctuations in these prices. In terms of crude oil and natural gas, part of this risk is transferred to the Mexican Government under PEMEX’s current fiscal regime. PEMEX’s exposure to hydrocarbon prices is partly mitigated by natural hedges between its inflows and outflows. Additionally, PEMEX continuously evaluates the implementation of risk mitigation strategies, including those involving the use of DFIs, taking into consideration their operative and budgetary feasibility. In 2017, the Board of Directors of Petróleos Mexicanos approved the establishment of an Annual Oil Hedging Program. Since then, PEMEX has implemented hedging strategies to partially protect its cash flows from falls in the Mexican crude oil basket price below the one established in the Federal Revenue Law. During 2019, PEMEX entered into a crude oil hedge for fiscal year 2020, pursuant to which PEMEX hedged 243 thousand barrels per day for the period between December 2019 and December 2020, for U.S.$178,268. Afterwards, during 2020 PEMEX entered into a crude oil hedge for the first half of fiscal year 2021, pursuant to which PEMEX hedged 332.5 thousand barrels per day for the period between December 2020 and June 2021, for U.S.$119,920. During the first half of 2021 PEMEX entered into a crude oil hedge for the second half of fiscal year 2021, pursuant to which PEMEX hedged 218 thousand barrels per day on average, for the period between July 2021 and December 2021, for U.S.$39,401. During the second half of 2021 and the first half of 2022, PEMEX entered into a crude oil hedge for the fiscal year 2022, pursuant to which PEMEX hedged 309 thousand barrels per day on average for the period between January 2022 and December 2022, for U.S.$158,988. Finally, during the second half of 2022, PEMEX entered into the crude oil hedge for the fiscal year 2023, pursuant to which PEMEX hedged 100 thousand barrels per day on average for the period between January 2023 and December 2023, for U.S.$69,652. Additionally, PEMEX cash flows are exposed to crack spread movements as these determine the refining margin. During the fourth quarter of 2022, PEMEX began the implementation of a hedging strategy to protect its cash flows exposed to diesel crack spread from decrements below the level established in the Federal Revenue Law for the fiscal year 2023. This is a zero-cost strategy. In addition to supplying natural gas, Pemex Industrial Transformation can offer DFIs to its domestic customers in order to provide them with support to mitigate the risk associated with the volatility of natural gas prices. Since 2017, when this service is offered, Pemex Industrial Transformation must enter into DFIs with Petróleos Mexicanos under the opposite position to those DFIs offered to its customers in order to mitigate the market risk it would bear under such offered DFIs. Petróleos Mexicanos then transfers the related price risk derived from the DFI position held with Pemex Industrial Transformation to financial counterparties by entering into the opposite position DFIs with such parties. As of December 31, 2022, there were no DFIs since all the DFIs in its portfolios expired in 2019. In case of entering into new trades, Pemex Industrial Transformation DFI portfolios have VaR and CaR limits in order to limit market risk exposure. PMI Trading faces market risk generated by the terms of the purchase and sale of refined products and natural gas liquids, as well as the volatility of oil prices. Accordingly, it frequently enters into DFIs in order to mitigate this risk, thereby reducing the volatility of its financial results. In accordance with the risk management regulatory framework that PMI Trading has implemented, VaR and the change in profit and loss by portfolio are calculated daily and compared to the maximum applicable limits in order to implement risk mitigation mechanisms as necessary. iv. Market risk quantification The quantification of market risk exposure in PEMEX’s financial instruments is presented below, in accordance with the applicable international risk management practices. Interest rate risk quantification The quantification of interest rate risk of investment portfolios is carried out by using the one-day horizon historical VaR, with a confidence level of 95%, over a period of one year. The VaR incorporates interest rate and spread risks. In addition, for portfolios in domestic currency, the VaR includes the inflation risk embedded in securities denominated in UDI. For portfolio management purposes, interest rate risk is mitigated by VaR limits. As of December 31, 2022, the VaRs of PEMEX’s investment portfolios were Ps. (15.15) for the Peso Treasury Portfolio, Ps. 0.00 for FOLAPE, and U.S.$ 0.00 for the U.S. Dollar Treasury Portfolio. Additionally, PEMEX has a portfolio of Mexican Government bonds. It is considered that these securities are not exposed to market risk, unlike the investment portfolios’ securities. Therefore, there is no need to calculate a VaR. In addition to the exposure to interest rate fluctuations of the DFIs in which PEMEX is obligated to make payments referenced to floating rates, PEMEX’s DFIs are exposed to Mark-to-Market (“MtM”) volatility as a result of changes in the interest rate curves used in their valuation. Interest rate risk quantification was calculated for DFIs in conjunction with the interest rate risk quantification for the debt portfolio. The following table shows the sensitivity of PEMEX’s DFIs and debt portfolio to a parallel shift of 10 basis points (bp) over the zero coupon rate curves. The 10bp parallel shift may be used to estimate in a simple manner the impact for proportional values to this shift and was selected in accordance with market practices for financial risk management. For the debt portfolio, interest rate risk sensitivity was calculated taking into account both the DFI interbank market yield curves and the PEMEX curves (which were also used to estimate the debt portfolios’ fair value). These metrics were calculated solely for informational purposes and are not used for portfolio management purposes because PEMEX does not intend to prepay its debt or terminate its DFIs early. Therefore, there is no interest rate risk arising from fixed rate obligations.

At December 31, 2022, 2021 and 2020, had market interest rates been 25 basis points higher, with all other variables remaining constant, the net income for the year ended December 31, 2022, would have been Ps. 796,763 lower, and the net loss for the years ended December 31, 2021 and 2020, would have been Ps. 895,382 and Ps. 606,839 higher, respectively, primarily as a result of an increase in interest expense. Conversely, had market interest rates been 25 basis points lower, the net income for the year ended December 31, 2022, would have been Ps. 796,763 higher, and the net loss for the years ended December 31, 2021 and 2020, would have been Ps. 895,382 and Ps. 606,839 lower, respectively, primarily as a result of a decrease in interest expense. Exchange rate risk quantification The investments of PEMEX’s portfolios do not face foreign exchange rate risk because the funds of such portfolios are used to meet obligations in pesos and U.S. dollars. Currency DFIs are entered into in order to hedge exchange rate risk arising from debt flows in currencies other than pesos and U.S. dollars or inflation risk arising from debt flows in UDIs. However, due to the accounting treatment, net income is exposed to MtM volatility, mainly as a result of changes in the exchange rates used in their valuation. Exchange rate risk quantification was calculated for DFIs in conjunction with the exchange rate risk quantification for the debt portfolio. The following table shows the sensitivity of PEMEX’s DFIs and debt portfolio to an increase of 1% to the exchange rates of currencies against the U.S. dollar. The 1% may be used to estimate in a simple manner the impact for proportional values to this increase and was selected in accordance with market practices for financial risk management. For the debt portfolio, exchange rate risk sensitivity was calculated taking into account both, interbank market yield curves and the PEMEX curves. In addition, the table shows the one-day horizon historical VaR of the remaining open position, with a confidence level of 95%, over a period of one year. These metrics were calculated solely for informational purposes. Nevertheless, in order to carry out management activities related to its debt portfolio, PEMEX periodically conducts quantitative analyses in order to estimate the exchange rate risk exposure generated by its debt issuances. Based on these analyses, PEMEX has elected to enter into DFIs as an exchange rate risk mitigation strategy. These DFIs along with the debt that they hedge are shown in the following table: INTEREST RATE and CURRENCY DFIs Exchange rate sensitivity +1% and VaR 95% Interbank Yield Curves Sensitivity VaR 95% PEMEX Curves Currency Sensitivity Sensitivity Sensitivity CHF U.S.$ (3,913) U.S.$ 3,964 U.S.$ 51 U.S.$ (42) U.S.$ (3,850) Euro (111,148) 76,215 (34,933) (36,092) (96,480) Pound Sterling (5,336) 5,334 (2) (3) (4,863) Yen (8,463) 2,045 (6,418) (7,542) (7,567) Peso (164,652) (17,471) (182,123) (165,737) (161,607) UDI (21,259) 20,794 (465) (435) (19,120) In thousands of U.S. dollars As shown in the table above, exchange rate risk derived from debt denominated in currencies other than pesos and U.S. dollars is almost fully hedged by DFIs. The exchange rate risk exposure to the Swiss franc, euro, pound sterling and Japanese yen is a result of the delta of the structures described above (Seagull Options and Calls), and considering the current exchange rate levels, represents a lower funding cost than the hedging strategies carried out through swaps. In addition, PEMEX performed a retrospective sensitivity analysis of the impact on its financial statements of the years ended December 31, 2022, 2021 and 2020, in which PEMEX assumed either an increase or decrease of 10% in the exchange rate between the U.S. dollar and peso in order to determine the impact on net income and equity as a result of applying these new rates to the monthly balances of assets and liabilities denominated in U.S. dollars. At December 31, 2022, 2021 and 2020, had the peso depreciated against the U.S. dollar by 10% with other variables remaining constant, the net income for the year ended December 31, 2022, would have been Ps. 198,697,226 lower, and the net loss for the years ended December 31, 2021 and 2020, would have been Ps. 172,056,924 and Ps. 168,334,391 higher, respectively, primarily as a result of an increase in the exchange rate losses. However, had the peso appreciated against the U.S. dollar by 10%, the net income for the year ended December 31, 2022, would have been higher by Ps. 198,697,226, and the net loss for the years ended December 31, 2021 and 2020, would have been lower by Ps. 172,056,924 and Ps. 168,334,391, respectively, primarily as a result of the decrease in exchange rate losses. Hydrocarbon price risk quantification Pemex Industrial Transformation occasionally faces market risk due to open positions arising from the mismatch between the DFI portfolio offered to domestic customers and hedges with international counterparties. As of December 31, 2022, Pemex Industrial Transformation’s natural gas DFI portfolios had no market risk exposure since all the DFIs in its portfolios expired in 2019. Open market risk exposure would be measured using the 20-day Delta-Gamma VaR methodology, with a confidence level of 95%, based on 500 daily observations; VaR and CaR would be monitored and mitigated by pre-established limits. It should be noted that sensitivity analyses were not carried out for other financial instruments, such as accounts receivable and payable (as defined in the financial reporting standards). Such accounts are cleared in short-term, and therefore market risk is considered to be nonexistent. Most of these accounts are related to hydrocarbon prices. In accordance with the risk management regulatory framework that PMI Trading has implemented, VaR and the change in profit and loss by portfolio are calculated daily and compared to the maximum applicable limits in order to implement risk mitigation mechanisms as necessary. PMI Trading’s global VaR associated with commodities market risk was U.S. $(4,064) as of December 31, 2022. This VaR was calculated using the historical method with a 95% confidence level, two-year history and a one-day horizon. The minimum VaR recorded on the year was U.S. $(2,504) (registered on December 12, 2022) and the maximum VaR recorded on the year was U.S. $(21,652) (registered on March 8, 2022). As of December 31, 2021, the global VaR 95% was U.S. $(4,614). The quantification of crude oil price risk is carried out by using the one-day horizon historical VaR, with a confidence level of 95%, over a period of one year. As of December 31, 2022, this was U.S.$(8,191). II. Credit Risk When the fair value of a DFI is favorable to PEMEX, PEMEX faces the risk that the counterparty will not be able to meet its obligations. PEMEX monitors its counterparties’ creditworthiness and calculates the credit risk exposure for its DFIs. As a risk mitigation strategy, PEMEX only enters into DFIs with major financial institutions with a minimum credit rating of BBB-. These ratings are issued and revised periodically by risk rating agencies. Furthermore, PEMEX seeks to maintain a diversified portfolio of counterparties. In order to estimate PEMEX’s credit risk exposure to each financial counterparty, the potential future exposure is calculated by projecting the risk factors used in the valuation of each DFI in order to estimate the MtM value for different periods, taking into account any credit risk mitigation provisions. Moreover, PEMEX has entered into various long-term cross-currency swaps agreements with “recouponing” provisions (pursuant to which the payments on the swaps are adjusted when the MtM exceeds the relevant threshold specified in the swap), thereby limiting the exposure to its counterparties to a specific threshold amount, as well as the counterparties’ exposure to PEMEX. The specified thresholds were reached in four cross-currency swap during 2022, which were used to hedge the exchange rate exposure to euro, and in one cross-currency swap during 2021, which was used to hedge the exchange rate exposure to the pounds sterling. This resulted in the cash settlement of such swaps and the resetting of swap terms to return their MtM value to zero. During 2022, PEMEX did not enter into any new cross-currency swap with these characteristics. Additionally, during 2022 PEMEX carried out a voluntary recouponing of a MXN/UDI cross-currency swap, which hedges an UDIs 721,564 debt with maturity in 2028. According to IFRS 13 “Fair Value Measurement,” the fair value or MtM value of DFIs must reflect the creditworthiness of the parties. Consequently, the fair value of a DFI takes into account the risk that either party may default on its obligation. Due to the above, PEMEX applies the credit value adjustment (“CVA”) method to calculate the fair value of its DFIs. For each DFI, the CVA is calculated by determining the difference between the MtM and the estimated MtM adjusted for credit risk. In determining the credit risk, the CVA method takes into account the current market perception about the credit risk of both counterparties, using the following inputs: a) the MtM projection for each

Employee Benefits

Employee Benefits	12 Months Ended

Disclosure of defined benefit plans [abstract]
Employee Benefits	EMPLOYEE BENEFITS Until December 31, 2015, Petróleos Mexicanos and Subsidiary Entities only had defined benefit pension plans for the retirement of its employees, to which only Petróleos Mexicanos and the Subsidiary Entities contribute. Benefits under these plans are based on an employee’s salary and years of service completed at retirement. As of January 1, 2016, Petróleos Mexicanos and the Subsidiary Entities also have a defined contribution pension plan, in which both Petróleos Mexicanos and the Subsidiary Entities and the employee contribute to an employee’s individual account. Benefits under the defined benefit plan are mainly based on the years of service completed by the employee, and their remuneration at the date of retirement. The obligations and costs of these plans are recognized based on an actuarial valuation prepared by independent experts. Within the regulatory framework of plan assets, there are no minimum funding requirements. Petróleos Mexicanos and the Subsidiary Entities have established additional plans to cover post-employment benefits, which are based on actuarial studies prepared by independent experts and which include disability, post-mortem pension and the death of retired employees, as well as medical services for retired employees and beneficiaries. For the defined benefit plan, Petróleos Mexicanos and Subsidiary Entities funded its employees benefits through Mexican trusts, the resources of which come from the retirement line item of PEMEX’s annual budget (an operating expense), or any other line item that substitutes or relates to this line item, or that is associated with the same line item and the interests, dividends or capital gains obtained from the investments of the trusts. In 2019, the Board of Directors of Petróleos Mexicanos approved modifications to the organic structure of PEMEX. As a result of this, the Subsidiary Entities and Petróleos Mexicanos transferred and / or received active personnel through the figure of employer substitution, with which the Subsidiary Entities and Petróleos Mexicanos recognized the retirement obligations of the transferred personnel whose impact was calculated in the actuarial study carried out by the independent experts. The following table show the amounts associated with PEMEX’s labor obligations: December 31, 2022 2021 Liability for defined benefits at retirement and post-employment at the end of the year Ps. 1,295,765,636 Ps. 1,371,307,692 Liability for other long-term benefits 11,121,039 12,763,956 Total liability for defined benefits recognized in the consolidated statement of financial position at the end of the year Ps. 1,306,886,675 Ps. 1,384,071,648 The amount reflected in Employee Benefit at the end of the year includes both the defined benefit plan (DB) and the defined contribution plan (DC). As for the defined contribution scheme, the Assets (liabilities) recognized in the balance sheet (DC-warranty) went from Ps. 2,417,049 in 2021 to Ps. 2,348,557 in 2022. The expense in the statement of comprehensive income (net cost for the period, DC-guarantee) was Ps. 452,913 and Ps.467,765 as of December 2022 and 2021, respectively. The following tables contain detailed information regarding PEMEX’s retirement and post-employment benefits: December 31, Changes in the liability for defined benefits 2022 2021 Liability for defined benefits at the beginning of the year Ps. 1,371,307,692 Ps. 1,516,671,029 Current Service cost (1) 18,446,170 41,135,899 Past service cost 524 34,573 Net interest 112,552,382 104,524,369 Liquidation event loss 1,971 49,032 Defined benefits paid by the fund (6,673,574) (6,608,749) Actuarial losses (gains) in other comprehensive results due to: Change in financial assumptions (2) (150,264,079) (266,985,561) Change in demographic assumptions (2) 2,403,864 44,085,779 For experience during the year (2) 16,188,726 2,581,184 Assets of the plan during the year (2) 277,256 (52,166) Contributions paid to the fund (68,475,296) (64,127,697) Defined benefit liabilities at end of year Ps. 1,295,765,636 Ps. 1,371,307,692 (1) The variation between 2022 and 2021 is mainly due to the result of the contractual review carried out in 2021, in which the retirement requirements were modified for the syndicated personnel. (2) The amount of actuarial losses corresponding to retirement and post-employment benefits recognized in other comprehensive income net of deferred income tax for Ps. (123,385,417) generated in the period from January to December 2022 correspond mainly to the increase in the discount rate from 8.46% in 2021 to 9.39% in 2022. Other influencing factors were the changes in obligations for movements in the population, age, seniority, salary, pensions and benefits. December 31, Changes in pension plan assets 2022 2021 Plan assets at the beginning of year Ps. 2,289,697 Ps. 2,438,724 Return on plan assets 253,721 294,713 Payments by the pension fund (68,534,502) (64,623,601) Company contributions to the fund 68,410,838 64,127,697 Actuarial (gains) losses in plan assets (121,876) 52,164 Adjustment to the Defined Contribution Plan (1) (64,388) — Pension plan assets at the end of year Ps. 2,233,490 Ps. 2,289,697 (1) The concepts come from the valuation of PMI´s liabilities. The Labor Fund reduction was due to budgetary requirements derived from the need to meet a financial balance goal in cash flow. In this sense, during 2020 PEMEX’s administration implemented a strategy and the contributions to the Fund are scheduled and executed taking into account the initial balance plus the cost of payrolls and retirements for the year, maintaining a minimum operating balance without the operational continuity risk or payment to personnel. The Contributions from PEMEX to the FOLAPE include the contribution associated to the Mexican Government Bonds exchanged, collected in December 2021 in the amount of Ps. 15,277,401 of principal, contributed during the months from January to March, 2022. Derived from the Federal Government Contribution due to the Modification of the Pension Plan of Petróleos Mexicanos and its Subsidiary Entities from April to December, 2022, PEMEX contributed to Ps. 7,544,895 of interest. From January 1 to December 31, 2022, interest income generated by the total of Government Bonds amounted Ps. 7,534,938 of which Petróleos Mexicanos received the payment of Ps. 7,455,715 (see Note 15). Expected payments for fiscal year 2023 are Ps. 85,750,924. As of December 31, 2022 and 2021, the amounts and types of plan assets are as follows: December 31, Plan Assets 2022 2021 Cash and cash equivalents Ps. 168,367 Ps. 32,199 Debt instruments 2,065,123 2,257,498 Total plan assets Ps. 2,233,490 Ps. 2,289,697 December 31, Changes in Defined Benefit Obligations (DBO) 2022 2021 Defined benefit obligations at the beginning of the year Ps. 1,373,548,493 Ps. 1,519,084,202 Service costs 17,582,708 21,151,945 Financing costs 112,801,977 104,844,611 Past service costs 524 34,573 Payments by the fund (75,208,077) (71,232,349) Amount of actuarial (losses) gains recognized in other comprehensive results due to: Change in financial assumptions (1) (150,264,079) (266,985,561) Change in demographic assumptions (2) 2,403,864 44,085,779 For experience during the year (3) 16,188,726 2,581,184 Reductions 1,971 — Modifications to the pension plan (4) 864,011 19,984,109 Defined benefit obligations at the end of year Ps. 1,297,920,118 Ps. 1,373,548,493 (1) The variations in financial assumptions are due to the increase in the discount rate from 8.46% in 2021 to 9.39% in 2022. (2) The main factor influencing in variation between 2022 and 2021 is due to the observed changes in mortality. (3) The changes in assumptions from experience depend on factors that do not necessarily have the same behavior from year to year and given by the movements in the population different to those expected, the factors that influenced the result of year 2022 were increase in salaries, departures and inflows of personnel, among others. (4) The variation between 2022 and 2021 is mainly due to the result of the contractual review carried out in 2021, in which the retirement requirements were modified for the syndicated personnel. The effects on the Defined Benefits Liability upon retirement and post-employment at the end of the period are: • The effect of an increase or decrease of one percentage point in the discount rate is a (10.39)% and 12.39%, respectively, in defined benefit obligations. • The effect of an increase or decrease of one percentage point in medical services is 2.48% and (2.20)%, respectively, in defined benefit obligations. • The effect of an increase or decrease of one percentage point in the inflation is 8.04% and (7.18)%, respectively, in defined benefit obligations. • The effect of an increase or decrease of one percentage point in the wage is 0.88% and (1.05)%, respectively, in defined benefit obligations. The effects previously mentioned were determined using the projected unit credit method which was the same method used in the prior valuation. Assumptions regarding future mortality are based on EMSSA2009 to Unique Circular of the Comisión Nacional de Seguros y Fianzas (National Commission of Insurance and Bonds) and include improvements. For the December valuation, the mortality table for retired personnel was updated using an actuarial proposal based on the experience of Petróleos Mexicanos and its Subsidiary Entities. The mortality table for the incapacitated personnel is the EMSSInc-IMSS2012 and for the disabled personnel the EMSSInv-IMSS2012. PEMEX’s plan assets is held in the FOLAPE trusts, which are managed by BBVA Bancomer, S. A. and a technical committee for each trust that is comprised of personnel from Petróleos Mexicanos and the trusts. As of December 31, 2022, FOLAPE has a balance of Ps. 167,023, while the remaining Ps. 2,066,467 belong to affiliate companies that are in charge of managing their own funds. The following tables present additional fair value disclosure about plan assets and indicate their rank, in accordance with IFRS 13, as of December 31, 2022 and 2021: Fair value measurements as of December 31, 2022 Plan assets Quoted prices in active markets for identical assets (level 1) Significant Significant Total Cash and cash equivalents Ps. 168,367 Ps. — Ps. — Ps. 168,367 Debt instruments 2,065,123 — — 2,065,123 Total Ps. 2,233,490 Ps. — Ps. — Ps. 2,233,490 Fair value measurements as of December 31, 2021 Plan assets Quoted prices in active markets for identical assets (level 1) Significant Significant Total Cash and cash equivalents Ps. 32,199 Ps. — Ps. — Ps. 32,199 Debt instruments 2,257,498 — — 2,257,498 Total Ps. 2,289,697 Ps. — Ps. — Ps. 2,289,697 As of December 31, 2022 and 2021, the principal actuarial assumptions used in determining the defined benefit obligation for the plans are as follows: December 31, 2022 2021 Rate of increase in salaries 4.47 % 4.47 % Rate of increase in pensions 4.00 % 4.00 % Rate of increase in post-mortem pensions 0.00 % 0.00 % Rate of increase in medical services 7.65 % 7.65 % Inflation assumption 4.00 % 4.00 % Rate of increase in basic basket for active personnel 5.00 % 5.00 % Rate of increase in basic basket for retired personnel 4.00 % 4.00 % Rate of increase in gas and gasoline 4.00 % 4.00 % Discount and return on plan assets rate (1) 9.39 % 8.46 % Average length of obligation (years) 13.45 14.38 (1) In accordance with IAS 19, the discount rate was determined using as a reference the interest rates observed in Mexican Government bonds, based on the Fixed Rate bonds of the Federal Government (“Bonos M”) and the “Cetes”, as well as the flow of expected payments to cover the contingent obligations. As a consequence of the change in the yields of the financial instruments mentioned above at the end of the year, the discount rate increased compared to the end of 2021. Other long-term benefits Petróleos Mexicanos and the Subsidiary Entities have established other long-term benefit plans for their employees, to which employees do not contribute, which correspond to the seniority premiums payable for disability, death and survivor benefits (payable to the widow and beneficiaries of worker), medical service, gas and basic basket for beneficiaries. Benefits under these plans are based on an employee’s salary and years of service completed at separation date. Obligations and costs of such plans are recorded in accordance with actuarial valuations performed by independent actuaries. The amounts recognized for other long-term obligations are as follows: December 31, Change in the liability for defined benefits 2022 2021 Liabilities for defined benefits at the beginning of year Ps. 12,763,956 Ps. 18,497,057 Charge to income for the year 2,010,051 2,354,238 Actuarial losses (gains) recognized in income due to: Change in financial assumptions (1,899,096) (4,121,075) Change in demographic assumptions (166,459) (2,027,902) For experience during the year (1,585,760) (1,937,645) Benefits paid (1,653) (717) Liabilities for defined benefits at the end of year Ps. 11,121,039 Ps. 12,763,956 The expected long-term benefit payments for 2023 amount to Ps. 326,674. The principal actuarial assumptions used in determining the defined benefit obligation for the plans are: • The effect of an increase or decrease of one percentage point in the discount rate is (14.12)% and 18.64%, respectively, in defined benefit obligations. • The effect of an increase or decrease of one percentage point in medical services is 6.79% and (4.55)%, respectively, in defined benefit obligations. • The effect of an increase or decrease of one percentage point in the inflation is 0.50% and (0.08)%, respectively, in defined benefit obligations. • The effect of an increase or decrease of one percentage point in the wage is 4.00% and (3.25)%, respectively in defined benefit obligations. The principal actuarial assumptions used in determining the defined benefit obligation for the plans are as follows: December 31, 2022 2021 Rate of increase in salaries 4.47 % 4.47 % Inflation assumption 4.00 % 4.00 % Rate of increase in basic basket for active personnel 5.00 % 5.00 % Rate of increase in basic basket for retired personnel 4.00 % 4.00 % Rate of increase in gas and gasoline 4.00 % 4.00 % Discount and return on plan assets rate (1) 9.39 % 8.46 % Average length of obligation (years) 13.45 14.38 (1) In accordance with IAS 19, the discount rate was determined using as a reference the interest rates observed in Mexican Government bonds denominated in pesos (Cetes and M bonds), as well as the flow of payments expected to cover contingent obligations. As a result of the profits in financial instruments at the end of 2022, the discount rate increased as compared 2021

The plugging provision represents the present value of plugging costs related to oil and gas properties. These provisions have been created based on internal estimates of PEMEX. PEMEX has made certain assumptions based on the current economic environment that PEMEX believes provide a reasonable basis on which to estimate the future liability. These estimates are reviewed regularly to take into account any material changes in the assumptions. However, actual plugging costs in the long run will depend on future market prices for the necessary plugging work, which reflect market conditions at the time the work is being performed. The calculation of this provision considers the year-end exchange rate, the projected inflation rate for the United States, interpolated discount rates based on the maturity date of long-term debt instruments in U.S. markets, as well as unit costs obtained from current contracts as of the valuation date, the current status of PEMEX’s wells and the limit of proved and developed reserves as of January 1, 2023. The decrease in the provision in 2022, 2021 and 2020 against fixed assets corresponded to a decrease in the reserve limits, adjustments to the discount rate and applications to the reserve. This includes the effect of the discount rate over time of Ps. 4,647,200, Ps. 4,454,106 and Ps. 4,555,692 for 2022, 2021 and 2020, respectively. The discount rate ranges used during 2022, 2021 and 2020 were from 9.380% to 10.520%, 3.114% to 8.040% and 3.268% to 7.799% for U.S. dollar denominated assets, respectively. Moreover, the time of plugging depends on when the fields cease to have economically viable production rates, which, in turn, depends on the inherently uncertain future prices of oil and gas. Well plugging of works will be carried out as follows: Year Amount 2023 Ps. 76,691 2024 1,064,330 2025 955,654 2026 4,350,081 2027 5,640,335 More than five years 54,612,297 Total Ps. 66,699,388 Provision for environmental costs PEMEX is subject to the provisions of the Ley General del Equilibrio Ecológico y la Protección al Ambiente (General Law on Ecological Equilibrium and Environmental Protection). To comply with this law, environmental audits of PEMEX’s larger operating, storage and transportation facilities have been or are being conducted. Following the completion of such audits, PEMEX has signed various agreements to implement environmental remediation and improve environmental plans. Such plans will be sent to the Agencia Nacional de Seguridad Industrial y de Protección al Medio Ambiente del Sector Hidrocarburos

The Hydrocarbons Revenue Law sets forth the fiscal regime for Petróleos Mexicanos applicable to the assignments and the contracts that were established on such date. Likewise, every year the Federal Revenue Law is published in the Official Gazette of the Federation and includes specific regulations for Petróleos Mexicanos and the Subsidiary Entities. Tax regime applicable to Assignments The tax regime applicable to the exploration and production for the assignments granted to PEMEX by the Mexican Government includes the following taxes and duties: A. Derecho por la Utilidad Compartida “DUC” (Profit-sharing Duty). As of January 1, 2015, Pemex Exploration and Production is obligated to pay a Profit-sharing Duty. For 2022 and 2021, the applicable rate of this duty was 40% and 54%, respectively. The computation of this duty is based on the excess of the value of hydrocarbons produced during the fiscal year (including self-consumption, shrinkage and burning), minus certain permitted deductions by the Hydrocarbons Revenue Law, including part of the investments and some costs, expenses and duties. Pursuant to the Federal Revenue Law, as of January 1, 2023, this duty was set at 40%. During 2022, this duty was Ps. 398,123,710 from annual payments presented on April 3, 2023 paid as follows: Ps. 397,567,229, resulting in a balance of Ps. 556,481 as of December 31, 2022. During 2021, this duty was Ps. 374,433,879 from annual payments presented on March 31, 2022 paid as follows: Ps. 300,374,423, in monthly installment payment and a tax credit of Ps. 73,280,000; resulting in a balance of Ps. 779,456 as of December 31, 2021. Duties and income tax paid as of December 31, 2022, 2021 and 2020 were Ps. 431,444,989, Ps. 265,883,549 and Ps. 172,369,522, respectively. The accounting result differs from the tax result mainly due to differences in depreciation, non-deductible expenses and others. Such differences generate a deferred DUC. Total DUC and other as of December 31, 2022, 2021 and 2020 are integrated as follows: 2022 2021 2020 DUC Ps. 398,123,710 374,433,879 218,912,687 Fiscal credit (1) — (73,280,000) (65,000,000) Deferred DUC expense (6,703,627) 5,673,403 696,449 Total DUC Ps. 391,420,083 306,827,282 154,609,136 (1) There was not credit tax granted for 2022. The principal factors generating the deferred DUC are the following: 2022 2021 Deferred DUC asset: Tax credits Ps. 454,631,317 571,306,914 Deferred Profit-sharing duty liability: Wells, pipelines, properties, plant and equipment (171,170,789) (241,237,295) Deferred DUC asset net 283,460,528 330,069,619 Unrecognized Deferred DUC (274,008,700) (327,321,418) Net, deferred DUC asset Ps. 9,451,828 2,748,201 The expected benefit for DUC in 2022 and 2021 was different from that which would result from applying the 40% and 54% rate to the tax base, respectively, as a result of the line items mentioned in the tables below. 2022 2021 2020 Expected expense (benefit): Ps. 236,421,472 147,520,595 (20,837,768) Increase (decrease) resulting from: Expected benefit contract (4,987,552) (5,333,064) (496,643) Non-cumulative profit (1) (778,566,830) (1,252,957,737) (2,291,937,519) Non-deductible expenses (1) 547,132,910 1,110,770,206 2,313,271,930 Production value 526,040,742 507,997,938 321,353,133 Deductible duties (51,920,424) (44,270,598) (21,850,672) DUC tax credit (2) — (73,280,000) (65,000,000) Deferred DUC (benefit) expense (6,703,627) 5,673,403 696,449 Deductions cap (75,996,608) (89,293,461) (80,589,774) DUC-Profit-sharing duty expense Ps. 391,420,083 306,827,282 154,609,136 (1) Fluctuations changes are included which have no effect on the determination of the DUC. (2) Corresponds to the tax credit granted by the Mexican Government on February 19, 2021 and April 21, 2020. On February 19, 2021, the Mexican Government, through a presidential decree, granted PEMEX a reduction in its tax burden equal to Ps. 73,280,000 for 2021. The tax benefit was granted as a measure of release of resources for PEMEX to increase investment in hydrocarbon exploration and production activities. This decrease in the Profit-sharing Duty is incremental to the one resulting from the decrease of the rate from 58% to 54% to in 2021 in accordance with amendments to the Hydrocarbons Revenue Law. B. Derecho de Extracción de Hidrocarburos (Hydrocarbons Extraction Duty). SHCP considers the effects of variations in the U.S. producer price index, or another alternative index, when it determines the rate to be published in the Official Gazette of the Federation. This duty is to be calculated using a rate based on a formula applicable to each type of hydrocarbon, the volume of production and utilizing the relevant market price for hydrocarbons in U.S. Dollars. During 2022 and 2021, Pemex Exploration and Production incurred Ps. 129,801,061 and Ps. 81,982,589 respectively, which are included in the cost of sales line item. C. Derecho de Exploración de Hidrocarburos (Exploration Hydrocarbons Duty). Pemex Exploration and Production as “assignee” must make monthly payments for this duty. The rates for 2022 were 1,548.88 pesos per square kilometer of non-producing areas. After 60 months, this tax increases to 3,703.86 pesos per square kilometer for each additional month that the area is not producing. These amounts will be updated on an annual basis in accordance with the national consumer price index. During 2022 and 2021, Pemex Exploration and Production incurred Ps. 1,638,913 and Ps. 1,443,437, respectively, which are included in the cost of sales line item. D. Impuesto por la actividad de Exploración y Extracción de Hidrocarburos (Exploration and Extraction Hydrocarbons Duty). The assignments granted by the Mexican Government create a tax on the exploration and extraction activities carried out in the corresponding area. The monthly tax paid during the exploration phase and until the extraction phase begins is 2,020.27 pesos per square kilometer. During the extraction phase of a project, a monthly tax of 8,081.17 pesos per square kilometer is payable until the relevant contract for exploration and extraction or assignment is terminated. During 2022 and 2021, the incurred tax was Ps. 4,664,541 and Ps. 4,701,122 respectively, which are included in the cost of sales line item. Tax Regime applicable to contracts: As of January 1, 2015, the tax regime applicable to Pemex Exploration and Production for contracts is set forth in the Hydrocarbons Revenue Law which regulates, among other things, the fiscal terms applicable to the exploration and extraction contracts (license, profit sharing contracts, production sharing and services) and sets duties and other taxes paid to the Mexican Government. The Hydrocarbons Revenue Law also establishes the following duties applicable to PEMEX in connection with assignments granted to it by the Mexican Government: • Cuota Contractual para la Fase Exploratoria (Exploration Phase Contractual Fee) During the exploration phase of an exploration and extraction contract, the Mexican Government is entitled to collect a monthly payment of 1,548.88 pesos per square kilometer of non-producing areas. After 60 months, this fee increases to 3,703.86 pesos per square kilometer for each additional month that the area is not producing. The fee amount will be updated on an annual basis in accordance with the national consumer price index. • Regalías (Royalties) Royalty payments to the Mexican Government are determined based on the “contractual value” of the relevant hydrocarbons, which is based on a variety of factors, including the type of underlying hydrocarbons (e.g., crude oil, associated natural gas, non-associated natural gas or condensates), the volume of production and the market price. Royalties are payable in connection with licensing contracts, production-sharing contracts and profit-sharing contracts. • Pago del Valor Contractual (Contractual Value Payment) Licensing contracts require a payment to the Mexican Government calculated as a percentage of the “contractual value” of the hydrocarbons produced, as determined by the SHCP on a contract-by-contract basis. • Porcentaje a la Utilidad Operativa (Operating Profit Payment) Production-sharing contracts and profit-sharing contracts require a payment equivalent to a specified percentage of operating profits. In the case of production-sharing contracts, this payment shall be made in-kind through delivery of the hydrocarbons produced. In the case of profit-sharing contracts, this payment shall be made in cash. • Bono a la Firma (Signing Bonus) Upon execution of a licensing contract, a signing bonus is to be paid to the Mexican Government in an amount specified by the SHCP in the relevant bidding terms and conditions or in the contracts resulting from a migration. • Impuesto por la actividad de Exploración y Extracción de Hidrocarburos (Hydrocarbons Exploration and Extraction Activities Tax) Contracts for exploration and extraction granted by the Mexican Government will include a specified tax on the exploration and extraction activities carried out in the relevant area. The monthly tax paid during the exploration phase and until the extraction phase begins is 2,020.27 pesos per square kilometer. During the extraction phase of a project, a monthly tax of 8,081.17 pesos per square kilometer is payable until the relevant contract for exploration and extraction or assignment is terminated. During 2022 and 2021 the incurred tax amounted to Ps. 226,653 and Ps. 211,095, respectively. Other applicable taxes The Subsidiary Entities are subject to the Income Tax Law and the Value Added Tax Law. Pemex Industrial Transformation is also subject to the Special Tax on Production and Services (IEPS Tax). 2022 indirect taxes are as listed below: A. IEPS Tax IEPS Sobre la Venta de los Combustibles Automotrices (IEPS Tax on the Sale of Automotive Fuels): This tax is a fee on domestic sales of automotive fuels, gasoline and diesel. Pemex Industrial Transformation collects the fee on behalf of the Mexican Government. The applicable fees for this tax are Ps. 5.49 per liter of gasoline with an octane rating lower than 91; 4.64 pesos per liter of gasoline with an octane rating greater than or equal to 91 and 6.04 pesos per liter of diesel. The amount of the fee will depend on the class of fuel. The fee is fixed yearly and adjusted on a weekly basis by the SHCP. The fees apply to sales in Mexico and imports. IEPS Beneficio de Entidades Federativas, Municipios y Demarcaciones Territoriales (IEPS Tax in Favor of States, Municipalities and Territories): This tax is a fee on domestic sales of automotive fuels, gasoline and diesel. Pemex Industrial Transformation collects the fee on behalf of the Mexican Government. The applicable fees for this tax are 48.47 cents per liter of gasoline with an octane rating of less than 91, 59.14 cents per liter of gasoline with an octane rating greater than or equal to 91 and 40.23 cents per liter of diesel. These fees change yearly in accordance with inflation. Funds gathered by this fee are allocated to Mexican states and municipalities as provided for in the Ley de Coordinación Fiscal (Tax Coordination Law). The fees only apply to sales in Mexico and are not subject to VAT. IEPS a los Combustibles Fósiles (IEPS Tax on Fossil Fuels): This tax is a fee on domestic sales of fossil fuels. Pemex Industrial Transformation collects the fee on behalf of the Mexican Government. The applicable fees for this tax are 8.30 cents per liter of propane, 10.74 cents per liter of butane, 14.56 cents per liter of gasoline and aviation fuel, 17.39 cents per liter of jet fuel and other kerosene, 17.66 cents per liter of diesel, 18.85 cents per liter of fuel oil, Ps. 21.88 per ton of petroleum coke, Ps. 51.29 per ton of coal coke, Ps. 38.62 per ton of mineral carbon and Ps. 55.83 per ton of carbon from other fossil fuels. These fees change yearly in accordance with inflation and apply to imports to Mexico. B. Value-Added Tax (“VAT”) For VAT purposes, final monthly payments are determined based on PEMEX’s cash flow, in accordance with the provisions of the Value Added Tax Law, applicable to payers of this tax. The general rate to be applied is 16%. Certain activities with incentives will have the rate of 0%. Beginning on January 1, 2019, a new Decree of fiscal incentives began to apply to the northern border region, which consisted of a credit equivalent to 50% of the general rate, applicable directly at the time of the sale or service. This incentive is applicable in six states in the northern border region and includes 43 municipalities in those states. Petróleos Mexicanos and its Subsidiary Entities apply this tax benefit to the operations they carry out within the municipalities of the States included in the Decree. VAT is applied to the sale of goods, the rendering of services, the granting of the temporary use of goods in the national territory and the importation of goods and services to the national territory. VAT taxpayers transfer VAT to their customers and are entitled to credit the VAT paid to their suppliers and on their imports. The net balance between VAT transferred to customers and paid to suppliers and on imports results each month in the VAT to be paid to the tax authorities or in an amount in favor of the taxpayer. The taxpayer has the right to credit VAT in favor against VAT payable in future months, to request a refund or to offset it against other payable federal taxes. Taxes on Income are described below: C. Income Tax As of January 1, 2015, Petróleos Mexicanos, the Subsidiary Entities and the Subsidiary Companies residing in Mexico for tax purposes are subject to the Income Tax Law. This tax is calculated by applying a rate of 30% to the tax result. Tax result is the excess of total revenues over the allowed deductions and tax losses from previous years. Accounting income differs from taxable income primarily due to the effects of inflation and differences between depreciation and other non-deductible expenses. For the years ended December 31, 2022, 2021 and 2020, Petróleos Mexicanos and its Subsidiary Companies incurred the following income tax expense (benefit): 2022 2021 2020 Current income tax Ps. 5,939,990 Ps. 3,573,731 Ps. 5,370,822 Deferred income tax (77,179,234) (3,052,891) 25,592,117 Total (benefit) expense income tax, net Ps.

These amounts are mainly from fiscal losses to be amortized amounting with an expiration year from 2026 to 2032. The principal factors generating the deferred income tax are the following: 2021 Recognized in Recognized in 2022 Deferred income tax asset: Provisions Ps. 11,032,260 888,794 — 11,921,054 Employee benefits provision 61,711,054 3,579,336 (8,075,854) 57,214,536 Advance payments from clients 176,967 43,248 — 220,215 Accrued liabilities 2,676,964 5,094,352 — 7,771,316 Non-recoverable accounts receivable 24,890 102,953 — 127,843 Derivative financial instruments 10,746 24,124 — 34,870 Wells, pipelines, properties and equipment 5,452,609 3,009,946 — 8,462,555 Tax loss carry-forwards (1) 8,468,185 67,960,156 — 76,428,341 Total deferred income tax asset 89,553,675 80,702,909 (8,075,854) 162,180,730 Deferred income tax liability: Wells, pipelines, properties, plant and equipment (1,191,034) (3,879,311) — (5,070,345) Other (2,150,316) 355,636 — (1,794,680) Total deferred income tax liability (3,341,350) (3,523,675) — (6,865,025) Net long-term deferred income tax asset Ps. 86,212,325 77,179,234 (8,075,854) 155,315,705 2020 Recognized in Recognized in 2021 Deferred income tax asset: Provisions Ps. 8,919,555 2,112,705 — 11,032,260 Employee benefits provision 71,640,981 3,652,157 (13,582,084) 61,711,054 Advance payments from clients 188,283 (11,316) — 176,967 Accrued liabilities 1,681,362 995,602 — 2,676,964 Non-recoverable accounts receivable 102,435 (77,545) — 24,890 Derivative financial instruments 41,735 (30,989) — 10,746 Wells, pipelines, properties and equipment 5,151,623 300,986 — 5,452,609 Tax loss carry-forwards (1) 12,427,658 (3,959,473) — 8,468,185 Total deferred income tax asset 100,153,632 2,982,127 (13,582,084) 89,553,675 Deferred income tax liability: Wells, pipelines, properties, plant and equipment (1,101,832) (89,202) — (1,191,034) Other (2,310,282) 159,966 — (2,150,316) Total deferred income tax liability (3,412,114) 70,764 — (3,341,350) Net long-term deferred income tax asset Ps. 96,741,518 3,052,891 (13,582,084) 86,212,325 (1) Tax loss carryforwards expire in 2031.

PEMEX’s Certificates of Contribution “A” are as follows: Amount Certificates of Contribution “A” as of December 31, 2020 Ps. 524,931,447 Increase in Certificates of Contribution “A” during 2021 316,354,129 Certificates of Contribution “A” as of December 31, 2021 Ps. 841,285,576 Increase in Certificates of Contribution “A” during 2022 188,306,717 Certificates of Contribution “A” as of December 31, 2022 Ps. 1,029,592,293 Mexican Government contributions made in the form of Certificates of Contribution “A” during 2022 totaled Ps. 188,306,717 and were designated for the construction of the Dos Bocas Refinery, for the strengthening of financial position and the rehabilitation plan of the National Refining System, as follows: Date Construction of the Dos Bocas Refinery Strengthening of financial position Rehabilitation Plan of the refineries January 21 — 19,321,641 — January 21 7,500,000 — — February 14 7,500,000 — — March 8 — 26,115,898 — March 8 7,500,000 — — April 28 762,100 — — May 26 21,737,900 — — July 29 — — 969,342 August 19 4,000,000 — — August 30 2,000,000 — — September 6 — — 683,125 September 8 2,500,000 — — September 14 2,500,000 — — September 22 2,500,000 — — September 28 2,400,000 — — October 4 — — 1,618,523 October 6 2,500,000 — — October 13 2,500,000 — — October 20 2,500,000 — — October 28 2,500,000 — — November 4 2,500,000 — — November 7 — — 1,805,296 November 10 2,500,000 — — November 17 2,500,000 — — November 25 — — 892,893 November 25 2,500,000 — — December 1 4,000,000 — — December 2 800,000 — — December 5 — — 1,200,000 December 8 4,000,000 — — December 15 4,000,000 — — December 15 — — 1,000,000 December 18 15,118,286 — 4,881,713 December 29 21,000,000 — — Total 129,818,286 45,437,539 Ps. 13,050,892 B. Mexican Government contributions During 2022, Petróleos Mexicanos received a grant from the FONADIN in the amount of Ps. 23,000,000 for the acquisition of the remaining 50.005% interest in DPRLP (see Note 12). During 2021, there were no Mexican Government contributions apart from Certificates of Contribution “A”. C. Legal reserve Under Mexican law, each of the Subsidiary Companies is required to allocate a certain percentage of its net income to a legal reserve fund until the fund reaches an amount equal to a certain percentage of each Subsidiary Company’s capital stock. During 2022 and 2021, there were no changes to the legal reserve. D. Accumulated other comprehensive income (loss) As a result of the discount rate analysis related to employee benefits liability, for the periods ended December 31, 2022 and 2021 PEMEX recognized net actuarial gains in other comprehensive income (loss) net of deferred income tax for Ps. 123,385,417 and Ps. 205,401,008, respectively, which included net of deferred income tax of Ps. (8,075,854) and Ps. (13,582,084), respectively, related to retirement and post-employment benefits. The variation related to retirement and post-employment benefits was the result of an increase in the discount and return on plan assets rates from 8.46% as of December 31, 2021 to 9.39% as of December 31, 2022. E. Accumulated deficit from prior years PEMEX has recorded negative earnings in the past several years. However, the Ley de Concursos Mercantiles (“Commercial Bankruptcy Law of Mexico”) is not applicable to Petróleos Mexicanos and the Subsidiary Entities. Furthermore, the financing agreements to which PEMEX is a party do not provide for financial covenants that would be breached or events of default that would be triggered as a consequence of negative equity. F. Uncertainty related to going concern The consolidated financial statements have been prepared assuming PEMEX will continue as a going concern. The going concern assumption contemplates the realization of assets and satisfaction of liabilities in normal course of business. However, substantial doubt about PEMEX’s ability to continue as a going concern exists. Facts and conditions PEMEX has substantial debt, incurred mainly to finance the capital expenditures needed to carry out its capital investment projects and to fund its operating expenses. Due to its heavy fiscal burden resulting from the payment of hydrocarbon extraction duties and other taxes, the cash flows derived from PEMEX’s operations in recent years have not been sufficient to fully fund its operations and capital expenditure programs, which have been partially supported by the Mexican Government's equity contributions. In addition, PEMEX´s working capital has deteriorated in recent years. In 2021 and 2022, certain ratings agencies downgraded PEMEX’s credit rating, mainly driven by the effects of COVID-19, as well the volatility of the crude oil prices and the downgrade of the Mexican Government’s sovereign debt rating, impacting PEMEX´s access to the financial markets, the cost and terms of PEMEX’s new debt and contract renegotiations that PEMEX may carry out during 2022 and 2023. These conditions have negatively impacted PEMEX´s financial performance and also its liquidity position. Although PEMEX recognized net income of Ps. 99,998,470 in 2022, during 2021 and 2020 PEMEX recognized losses of Ps. (294,775,877) and Ps. (509,052,065), respectively. In addition, as of December 31, 2022 and 2021, PEMEX had a negative equity of Ps. (1,768,822,225), and Ps. (2,170,000,783), respectively, mainly due to continuous net losses, and a negative working capital of Ps. 401,842,480 and Ps. 464,254,286, as of December 31, 2022 and 2021, respectively. PEMEX has budget autonomy, and, in public finance terms, is subject to the cash flows financial balance goals approved in the Decreto de Presupuesto de Egresos de la Federación (“Federal Expenditure Budget Decree”). This represents the difference between its gross revenues (inflows) and its total budgeted expenditures (outflows) including the financial cost of its debt, which is proposed by the SHCP and approved by the Chamber of Deputies. The Federal Budget for 2022 authorized PEMEX to have a negative financial balance budget of Ps. zero. This shortfall does not consider payments of principal of PEMEX’s debt due in 2023 which will be covered by financing activities that do not represent a net debt in terms of public debt greater than Ps. 29,912,400. PEMEX has short-term debt principal maturities (including interest payable) of Ps.465,947,683 as of December 31, 2022. The combined effect of the above-mentioned events indicates substantial doubt about PEMEX’s ability to continue as a going concern. Actions- PEMEX and the Mexican Government are carrying out the following actions, among others, to preserve liquidity and let PEMEX pay its commitments: The application of the tax credit decree to automotive fuels published in the Official Gazette of the Federation of March 4, 2022, remains for 2023, which allows PEMEX to substantially recover the value of the difference between the sale price and its international reference price, when in a scenario of oil and diesel, these are limited to the effects of inflation in the country. The reduction of the profit-sharing duty rate remains for 2023, as in 2022, since the decreased to 40.0% in 2022 from 54.0% in 2021. During early 2023, PEMEX received equity contributions of P.s 7,200,000 and issued notes totaling Ps. 41,200,000. In addition, PEMEX has plans to raise funds from the markets in accordance with prevailing conditions, to refinance its debt. Further, PEMEX has the capacity to refinance its short-term debt maturities through direct loans and revolving credit facilities and loans guaranteed by export credit agencies. PEMEX also established in conjunction with development and commercial banks Cadenas Productivas PEMEX Plus (Productive Chains Plus Program) to aid for the payment to suppliers and contractors. PEMEX's ability to refinance its short-term debt depends on factors beyond its reach. The Revenue Law for 2022 also authorized PEMEX to incur a net additional indebtedness up to Ps. 29,912,400 (Ps. 27,068,400 and U.S.$142,200), which is considered as public debt by the Mexican Government and may be used to partially cover its financial balance of zero in 2023. PEMEX reviews and aligns its capital expenditures portfolio in accordance with updated economic assumptions on a periodic basis and giving priority to those projects which increase production in an efficient manner and at the lowest cost. On December 13, 2022, the Board of Directors of Petróleos Mexicanos approved the business plan of Petróleos Mexicanos and its Subsidiary Companies for 2023-2027 (the “2023-2027 Business Plan”). Prices of crude oil, natural gas and petroleum products shown a recovery in 2022, and they are expected to continue recover during 2023. In addition, if international values for the Mexican oil price were higher than the average price of U.S. $68.7 per barrel, the price on which the zero financial balance was built, this additional revenue would enable PEMEX to achieve its business plan objectives more quickly. Petróleos Mexicanos and its Subsidiary Entities are not subject to the Commercial Bankruptcy Law of Mexico and none of PEMEX’s existing financing agreements include any financial covenants that could lead to the demand for immediate payment of its debt due to having negative equity or non-compliance with financial ratios. As a reference, PEMEX prepared its consolidated financial statements as of December 31, 2022 and 2021 on a going concern basis. There are certain conditions that have generated important uncertainty and significant doubts concerning the entity’s ability to continue operating, including recurring net losses, negative working capital and negative equity. Those financial statements do not contain any adjustments that would be required if they were not prepared on a going concern basis. G. Non-controlling interest PEMEX does not currently own all of the shares of PMI CIM and COMESA, variations in income and equity from these entities are also presented in the consolidated statements of changes in equity (deficit) as “non-controlling interest.” As of December 31, 2022, 2021 and 2020 non-controlling interest represented (losses) gains of Ps. (288,610), Ps. 128,502 and Ps. 369,692, respectively, in PEMEX’s equity (deficit).

Pemex Logistics determines the volume of missing hydrocarbons through monthly calculations. (2) The variation in inventories represents the difference between the balances as of the beginning and the end of the year, as well as variations in standard and real costs. During 2022, the variation was mainly due to the increase in crude oil prices.

Disclosure of contingent liabilities [abstract]
Contingencies	CONTINGENCIESIn the ordinary course of business, PEMEX is named in a number of lawsuits of various types. PEMEX evaluates the merit of each claim and assesses the likely outcome. PEMEX has not recorded provisions related to ongoing legal proceedings since an unfavorable resolution is not expected in such proceedings, with the exception of the proceeding described in further detail in this Note. PEMEX is involved in various civil, tax, criminal, administrative, labor and commercial lawsuits and arbitration proceedings. The results of these proceedings are uncertain as of the date of these consolidated financial statements. As of December 31, 2022 and 2021, PEMEX had accrued a reserve of Ps. 10,533,137 and Ps. 11,114,006, respectively, for these contingent liabilities. As of December 31, 2022, the current status of the principal lawsuits in which PEMEX is involved is as follows: • On April 4, 2011, Pemex Exploration and Production was summoned before the Séptima Sala Regional Metropolitana (“Seventh Regional Metropolitan Court”) of the Tribunal Federal de Justicia Fiscal y Administrativa (“Tax and Administrative Federal Court”) in connection with an administrative claim (No. 4957/11-17-07-1) filed by EMS Energy Services de México, S. de R.L. de C.V. and Energy Maintenance Services Group I. LLC requesting that Pemex Exploration and Production’s termination of the public works contract be declared null and void. In a concurrent proceeding, the plaintiffs also filed an administrative claim (No. 13620/15-17-06) against Pemex Exploration and Production before the Sexta Sala Regional Metropolitana (“Sixth Regional Metropolitan Court”) of the Tax and Administrative Federal Court in Mexico City seeking damages totaling U.S. $193,713 related to the above-mentioned contract. Pemex Exploration and Production filed a response requesting the two administrative claims be joined in a single proceeding, which was granted. On April 30, 2019, a judgment was issued by the Segunda Seccion de la Sala Superior (“Second Section of the Superior Court”) in favor of Pemex Exploration and Production. On June 25, 2019, the plaintiffs filed an amparo (D.A. 397/2019) before the Tercer Tribunal Colegiado en Materia Administrativa del Primer Circuito (“Third Administrative Joint Court of the First Circuit”), which was granted. On March 12, 2020, Pemex Exploration and Production filed a motion to review against the resolution granting this amparo before the Third Administrative Joint Court of the First Circuit . On October 1, 2020, the Third Administrative Joint Court declared the resolution null and void, no amount was granted in favor of the plaintiffs, among others. On February 24, 2022, an amparo (350/2020) was granted in favor of EMS Energy Services de México, S. de R.L. On March 17, 2022, a motion was filed to draw the resolution by the Suprema Corte de Justicia de la Nación (Supreme Court of Justice of the Nation).

Supplementary Information On Oil and Gas Exploration And Production Activities (Unaudited)	SUPPLEMENTARY INFORMATION ON OIL AND GAS EXPLORATION AND PRODUCTION ACTIVITIES (UNAUDITED) Under the Mexican Constitution, all crude oil and other hydrocarbon reserves located in the subsoil of Mexico are owned by the Mexican nation and not by PEMEX. In August 2014, through the Round Zero process, the Mexican Government granted PEMEX the right to extract, but not own, certain petroleum and other hydrocarbon reserves in Mexico through assignment deeds. This note provides supplementary information on the oil and gas exploration, development and production activities of Pemex Exploration and Production in compliance with the U.S. Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 932 10-5 “Extractive Activities—Oil and Gas” (“ASC Topic 932”) and Accounting Standards Update 2010-03 (see Note 3-G). As of the date of these consolidated financial statements, all exploration and production activities of Pemex Exploration and Production are conducted in Mexico.

E. Crude oil and natural gas reserves (unaudited) Under the Mexican Constitution, all oil and other hydrocarbon reserves located in the subsoil of Mexico are owned by the Mexican nation and not by PEMEX. Under the Petróleos Mexicanos Law, Pemex Exploration and Production has the right to extract, but not own, these reserves, and to sell the resulting production. The exploration and development activities of Petróleos Mexicanos and the Subsidiary Entities are limited to reserves located in Mexico. Proved oil and natural gas reserves are those estimated quantities of crude oil, natural gas and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be economically producible from a given date forward, from known reservoirs and under existing economic conditions, operating methods and government regulations. Proved reserves estimates as of December 31, 2022 were prepared by the Exploration and Production segment and were reviewed by the Independent Engineering Firms (as defined below), which audit its estimates of hydrocarbon reserves. According to the Lineamientos que Regulan los Procedimientos de Cuantificación y Certificación de Reservas de la Nación (Guidelines for Regulating the Nation’s Reserves Quantification and Certification Procedures), CNH should review and approve of Hydrocarbons Reserves reports of Mexico’s operators in the month of April. As of the date of these consolidated financial statements, the proved reserves estimates as of December 31, 2022 have not been approved by the CNH. Pemex Exploration and Production estimates proved reserves based on generally accepted petroleum engineering and evaluation methods and procedures, which are based primarily on applicable SEC regulations and, as necessary, the SPE’s publication entitled Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information, dated June 25, 2019 and other SPE publications, including the SPE’s publication entitled Petroleum Resources Management System, as well as other technical sources, including Estimation and Classification of Reserves of Crude Oil, Natural Gas, and Condensate, by Chapman Cronquist, and Determination of Oil and Gas Reserves, Petroleum Society Monograph Number 1, published by the Canadian Institute of Mining and Metallurgy & Petroleum. The choice of method or combination of methods employed in the analysis of each reservoir is determined by: • Experience in the area • Stage of development • Quality and completeness of basic data • Production and pressure histories Reserves data set forth herein represents only estimates. Reserves valuation is a subjective process of estimating underground accumulations of crude oil and natural gas that cannot be measured in an exact manner. The accuracy of any reserves estimate depends on the quality of available data, engineering and geological interpretation and professional judgment. As a result, estimates of different engineers may vary. In addition, the results of drilling, testing and producing subsequent to the date of an estimate may lead to the revision of an estimate. During 2022, PEMEX did not record any material increase in PEMEX’s hydrocarbons reserves as a result of the use of new technologies. In order to ensure the reliability of PEMEX’s reserves estimation efforts, it has undertaken the internal certification of its estimates of reserves since 1996. PEMEX has established certain internal controls in connection with the preparation of its proved reserves estimates. Initially, teams of geoscientists from Pemex Exploration and Production’s exploration and exploitation business units (with each of these units covering several projects) prepare the reserves estimates, using different estimation processes for valuations relating to new discoveries and developed fields, respectively. Subsequently, the regional reserves offices collect these reserves estimates from the units and request that the Gerencia de Certificación de Reservas de Hidrocarburos , (Office of Hydrocarbon Reserves Certification), the central hydrocarbon reserves management body of Pemex Exploration and Production, review and certify such valuations and the recording of the related reserves. This internal certification process is undertaken in accordance with internal guidelines for estimating and classifying hydrocarbon reserves, which are based on the SEC’s rules and definitions. The Office of Hydrocarbon Reserves Certification, which additionally oversees and conducts an internal audit of the above process, consists entirely of professionals with geological, geophysical, petrophysical and reservoir engineering backgrounds. The engineers who participate in PEMEX’s reserves estimation process are experienced in the following areas: reservoir numerical simulation; well drilling and completion; pressure, volume and temperature (PVT) analysis; analytical tools used in forecasting the performance of the various elements comprising the production system; and design strategies in petroleum field development. Furthermore, all of PEMEX’s personnel have been certified by the Secretaría de Educación Pública (Ministry of Public Education), most have earned master’s degrees in areas of study such as petroleum engineering, geology and geophysical engineering and they possess an average of over fifteen years of professional experience. In addition to this internal review process, Pemex Exploration and Production’s final reserves estimates are audited by independent engineering firms. Four independent engineering firms audited Pemex Exploration and Production’s estimates of proved reserves as of December 31, 2022 or January 1, 2023: DeGolyer and MacNaughton (“DeGolyer”), Ryder Scott Company L.P (“Ryder Scott”), GLJ LTD. (“GLJ”) and Sproule International Limited and Sproule México, S.A. de C.V. (which we refer to as “Sproule”), together, the “Independent Engineering Firms.” The reserves estimate reviewed by the Independent Engineering Firms totaled 83.7% of PEMEX’s estimated proved reserves. The remaining 16.3% of PEMEX’s estimated proved reserves consisted of reserves located, among others, in some fields related to exploration and production contracts, in which a corresponding third party is responsible for assessing the volume of reserves. DeGolyer audited the reserves in the Cantarell, Ku Maloob Zaap, Bellota Jujo and Samaria Luna business units, GLJ audited the reserves in the Poza Rica Altamira, Abkatún Pol Chuc and Litoral de Tabasco business units, Sproule audited the reserves in the Cinco Presidentes and Macuspana Muspac business units and Ryder Scott audited the reserves in the Reynosa, Veracruz business units and the reserves of fields recently added to Pemex´s inventory reserves. The audits conducted by the Independent Engineering Firms consisted primarily of: (1) analysis of historical static and dynamic reservoir data provided by Pemex Exploration and Production; (2) construction or updating of the Independent Engineering Firms’ own static and dynamic reservoir characterization models of some of the fields; (3) economic analysis of the fields; and (4) review of Pemex Exploration and Production’s production forecasts and reserves estimates. Since reserves estimates are, by definition, only estimates, they cannot be reviewed for the purpose of verifying exactness. Instead, the Independent Engineering Firms conducted a detailed review of Pemex Exploration and Production’s reserves estimates so that they could express an opinion as to whether, in the aggregate, the reserves estimates that Pemex Exploration and Production furnished were reasonable and had been estimated and presented in conformity with generally accepted petroleum engineering and evaluation methods and procedures. All questions, including any suggested modifications to proved reserves estimates, that arose during the Independent Engineering Firms’ review process were resolved by Pemex Exploration and Production to the satisfaction of the Independent Engineering Firms. The Independent Engineering Firms have concluded that PEMEX’s estimated total proved oil and natural gas reserve volumes set forth in this report are, in the aggregate, reasonable and have been prepared in accordance with Rule 4-10(a) are consistent with international reserves reporting practice and are in accordance with the revised oil and gas reserves disclosure provisions of ASC Topic 932. PEMEX´s total proved developed and undeveloped reserves of crude oil, condensates and liquefiable hydrocarbons recoverable from field processing plants increased by 0.3% in 2022, from 6,073.0 million barrels on December 31, 2021 to 6,089.6 million barrels at December 31, 2022. Our proved developed reserves of crude oil, condensates and liquefiable hydrocarbons recoverable from processing plants increased by 1.4% in 2022, from 3,648.9 million barrels on December 31, 2021 to 3,698.3 million barrels at December 31, 2022. The amount of our proved reserves of crude oil, condensate and liquefiable hydrocarbon reserves added in 2022 was enough to offset the level of production in 2022, which amounted to 710.2 million barrels of crude oil, condensates and liquefiable hydrocarbons. Our total proved developed and undeveloped dry gas reserves increased by 0.6% in 2022, from 7,039.5 billion cubic feet at December 31, 2021 to 7,079.6 billion cubic feet on December 31, 2022. Our proved developed dry gas reserves increased by 11.1% in 2022, from 3,933.7 billion cubic feet on December 31, 2021 to 4,368.5 billion cubic feet at December 31, 2022. These increases were principally due to an increase in proved developed dry gas reserves of the Quesqui, Lakach, Onel, Gasífero, Ku, and Tupilco Profundo fields. The amount of dry gas reserves added in 2022 was enough to offset the level of production in 2022, which amounted to 854.0 billion cubic feet of dry gas. Our proved undeveloped dry gas reserves decreased by 12.7% in 2022, from 3,105.8 billion cubic feet at December 31, 2021 to 2,711.1 billion cubic feet on December 31, 2022. This decrease was principally due to an increase in in proved developed dry gas reserves of the Quesqui, Ixachi, Gasífero, Ku, Onel and Tupilco Profundo fields. During 2022, our exploratory activity in the shallow waters of the Gulf of Mexico and onshore regions resulted in the discovery of eleven new crude oil fields (Actul, Akal NW, Atoyatl, Chucox, Chucox NW, Pokche-NE, Tentok, Tlalkivak, Xanab-SE, Xinich and Zama) and one new reservoir in existing field (Niquita) and an extension from the drilling of one appraisal well in existing field (Valeriana ). Together, these extensions and discoveries led to the incorporation approximately 89.1 million barrels of oil equivalent. The following three tables of crude oil and dry gas reserves set forth PEMEX’s estimates of its proved reserves determined in accordance with Rule 4-10(a). Summary of oil and gas (1) proved reserves as of December 31, 2022 based on average fiscal year prices Crude oil and Condensates (2) Dry Gas (3) (in millions (in billions Proved developed and undeveloped reserves: Proved developed reserves 3,698.3 4,368.5 Proved undeveloped reserves 2,391.3 2,711.1 Total proved reserves 6,089.6 7,079.6 Note: Numbers may not total due to rounding. (1) PEMEX does not currently produce synthetic oil or synthetic gas, or other natural resources from which synthetic oil or synthetic gas can be produced. (2) Crude oil and condensate reserves include the fraction of liquefiable hydrocarbons recoverable in natural gas processing plants located at fields. (3) Reserve volumes reported in this table are volumes of dry gas, although natural gas production reported in other tables refers to sour wet gas. There is a shrinkage in volume when natural gas liquids and impurities are extracted to obtain dry gas. Therefore, reported natural gas volumes are greater than dry gas volumes.

Source: Pemex Exploration and Production. Pemex Exploration and Production’s reserve-replacement ratio, or RRR, for a given period is calculated by dividing the sum of proved reserves additions due to discoveries, developments, delineations and revisions by that period’s total production. During 2022, we obtained an increase of 898.7 million barrels of oil equivalent of proved reserves as aggregated from discoveries, revisions, delimitations and development and production, which represents a RRR of 102.8%. PEMEX’s 2022 RRR improved similarly to that of 2021, when the RRR was 105.1%. PEMEX expect to continue obtaining values of this index of about 100 percent, as in the recent years. PEMEX’s reserves production ratio, which is presented in terms of years, is calculated by dividing the estimated remaining reserves at the end of the relevant year by the total production of hydrocarbons for that year. As of December 31, 2022, this ratio is eight years, six months for proved reserves. F. Standardized measure of discounted future net cash flows related to proved oil and gas reserves (unaudited) The standardized measure tables presented below relate to proved oil and gas reserves excluding proved reserves scheduled to be produced after the year 2048. This measure is presented in accordance with ASC Topic 932. Estimated future cash inflows from production are computed by applying average prices of oil and gas on the first day of each month of 2022. Future development and production costs are those estimated future expenditures needed to develop and produce the year-end estimated proved reserves after a net cash flows discount factor of 10%, assuming constant year-end economic conditions. Future tax expenses are computed by applying the appropriate year-end statutory tax rates with consideration of the tax rates of the new fiscal regime for Pemex Exploration and Production already legislated for 2022 to the future pre-tax net cash flows related to PEMEX’s proved oil and gas reserves. The estimated future payment of taxes was calculated based on the current Hydrocarbons Revenue Law. The standardized measure provided below represents a comparative benchmark value rather than an estimate of expected future cash flows or fair market value of PEMEX’s production rights. There are numerous uncertainties inherent in estimating quantities of proved reserves and in projecting future rates of production and timing of development expenditures, including many factors beyond the control of the producer. Accordingly, reserve estimates may be materially different from the quantities of crude oil and natural gas that are ultimately recovered. Standardized measure of discounted future net cash flows as of December 31 2022 2021 2020 (in millions of U.S. dollars) Future cash inflows 512,547 371,331 201,777 Future production costs (excluding profit taxes) (174,115) (146,062) (109,064) Future development costs (26,013) (24,184) (23,631) Future cash flows before tax 312,419 201,085 69,082 Future production and excess gains taxes (205,035) (146,416) (73,122) Future net cash flows 107,384 54,669 (4,040) Effect of discounting net cash flows by 10% (44,461) (18,443) 3,359 Standardized measure of discounted future net cash flows 62,923 36,226 (681) Note: Table amounts may not total due to rounding. To comply with ASC Topic 932, the following table presents the aggregate standardized measure changes for each of the last three years and significant sources of variance: Changes in standardized measure of discounted future net cash flows 2022 2021 2020 (in millions of U.S. dollars) Sales of oil and gas produced, net of production costs (54,470) (34,600) (16,968) Net changes in prices and production costs 77,278 84,233 (39,509) Extensions and discoveries 3,078 1,583 1,426 Development cost incurred during the year 5,738 4,755 4,654 Changes in estimated development costs (5,523) (5,675) (10,019) Reserves revisions and timing changes 15,773 26,205 5,808 Accretion of discount of pre-tax net cash flows 9,749 2,220 5,929 Net changes in production and excess gains taxes (24,927) (41,814) 23,015 Aggregate change in standardized measure of discounted future net cash flows 26,696 36,907 (25,664) Standardized measure: As of January 1 36,226 (681) 24,983 As of December 31 62,922 36,226 (681) Change 26,696 36,907 (25,664) Note: Table amounts may not total due to rounding. In computing the amounts under each factor of change, the effects of variances in prices and costs are computed before the effects of changes in quantities. Consequently, changes in reserves are calculated at December 31 prices and costs.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	12 Months Ended

Disclosure of voluntary change in accounting policy [abstract]
Basis of consolidation	A. Basis of consolidation The consolidated financial statements include the financial statements of Petróleos Mexicanos and those of its subsidiaries over which it has control. i. Business combinations PEMEX accounts for business combinations using the acquisition method when the acquired set of activities and assets meets the definition of a business and control is transferred to PEMEX. In determining whether a particular set of activities and assets is a business, PEMEX assesses whether the set of assets and activities acquired includes, at a minimum, an input and substantive process and whether the acquired set could produce outputs. PEMEX has an option to apply a ‘concentration test’ that permits a simplified assessment of whether an acquired set of activities and assets is not a business. The optional concentration test is met if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. The consideration transferred in the acquisition is generally measured at fair value, as are the identifiable net assets acquired. Any goodwill that arises is tested annually for impairment. Any gain on a bargain purchase is recognized in profit or loss immediately. Transaction costs are expensed as incurred, except if related to the issue of debt or equity securities. Any contingent consideration is measured at fair value at the date of acquisition. If an obligation to pay contingent consideration that meets the definition of a financial instrument is classified as equity, then it is not remeasured and settlement is accounted for within equity. Otherwise, other contingent consideration is remeasured at fair value at each reporting date and subsequent changes in the fair value of the contingent consideration are recognized in profit or loss. ii. Subsidiaries Subsidiaries are entities controlled by PEMEX. PEMEX “controls” an entity when it is exposed to, or has rights to, variable returns from its involvement with the entity and could affect those returns through its power over the entity. The financial statements of subsidiaries are included in the consolidated financial statements from the date on which control commences until the date on which control ceases. For more information about the Subsidiary Companies, see Note 5. iii. Non-controlling interests (NCI) NCI are measured initially at their proportionate share of the acquiree’s identifiable net assets at the date of acquisition. Changes in the ownership interest in a subsidiary that do not result in a loss of control are accounted for as equity transactions. iv. Loss of control When PEMEX loses control over a subsidiary, it derecognizes the assets and liabilities of the subsidiary, and any related NCI and other components of equity. Any resulting gain or loss is recognized in profit or loss. Any interest retained in the former subsidiary is measured at fair value when control is lost. v. Interests in equity-accounted investees PEMEX’s interests in equity-accounted investees comprise interests in associates and a joint venture. Associates are those entities in which PEMEX has significant influence, but not control or joint control, over the financial and operating policies. A joint venture is an arrangement in which PEMEX has joint control, whereby PEMEX has rights to the net assets of the arrangement, rather than rights to its assets and obligations for its liabilities (joint operation). Interests in associates and the joint venture are accounted for using the equity method. They are initially recognized at cost, which includes transaction costs. Subsequent to initial recognition, the consolidated financial statements include PEMEX’s share of the profit or loss and other comprehensive income (OCI) of equity accounted investees, until the date on which significant influence or joint control ceases. Upon loss of significant influence over the associate or joint control over the joint venture, PEMEX measures and recognizes any retained investment at its fair value. Any difference between the carrying amount of the associate or joint venture upon loss of significant influence or joint control and the fair value of the retained investment and proceeds from disposal is recognized in profit or loss. When the value of the share of losses exceeds the value of PEMEX’s investment in an associate or joint venture, the carrying value of the investment, including any long-term investment, is reduced to zero and PEMEX ceases to recognize additional losses, except in cases where PEMEX is liable for obligations incurred by those associates and joint ventures. For more information about joint ventures and associates, see Note 12. vi. Transactions eliminated on consolidation Intra-group balances and transactions, and any unrealized income and expenses arising from intra-group transactions, are eliminated. Unrealized gains arising from transactions with equity-accounted investees are eliminated against the investment to the extent of the PEMEX interest in the investee. Unrealized losses are eliminated in the same way as unrealized gains, but only to the extent that there is no evidence of impairment.
Foreign currency	B. Foreign currency i. Foreign currency transactions Transactions in foreign currencies are translated into the respective functional currencies of PEMEX companies at the exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency at the exchange rate at the reporting date. Non-monetary assets and liabilities that are measured at fair value in a foreign currency are translated into the functional currency at the exchange rate when the fair value was determined. Non-monetary items that are measured based on historical cost in a foreign currency are translated at the exchange rate at the date of the transaction. Foreign currency differences are generally recognized in consolidated statements of comprehensive income and presented within foreign exchange. ii. Foreign operation The financial statements of foreign subsidiaries and associates are translated into the reporting currency by first identifying if the functional currency is different from the currency for recording the foreign operations, and, if so, the recording currency is translated into the functional currency and then into the reporting currency using the year-end exchange rate of each period for assets and liabilities reported in the consolidated statements of financial position; the historical exchange rate at the date of the transaction for equity items; and the exchange rate at the date of the transaction for income and expenses reported in the consolidated statement of comprehensive income. Foreign currency differences are recognized in OCI and accumulated in the currency translation effect, except to the extent that the translation difference is allocated to NCI.
Financial instruments	C. Financial instruments i. Recognition and initial measurement Financial assets and liabilities are initially recognized when these assets are contractually originated or acquired, or when these liabilities are contractually issued or assumed. Financial assets and financial liabilities (unless it is an account receivable or account payable without a significant financing component) are measured and initially recognized at fair value, in the case of financial assets or liabilities not measured at fair value with changes through OCI, plus the transaction costs directly attributable to acquisition or issuance, when subsequently measured at amortized cost. An account receivable or account payable without a significant financing component is initially measured at the transaction price. If PEMEX determines that the fair value at the initial recognition differs from the transaction price, PEMEX shall recognize the difference between the fair value at initial the recognition and the transaction price in the consolidated statements of comprehensive income. ii. Classification and subsequent measurement Financial Assets On initial recognition, a financial asset is classified as measured at: Amortized Cost; Fair Value Through Other Comprehensive Income (“FVTOCI”)–debt investment; FVTOCI–equity investment; or Fair Value Through Profit or Loss (“FVTPL”). Financial assets are not reclassified subsequent to their initial recognition unless PEMEX changes its business model for managing financial assets, in which case all affected financial assets are reclassified on the first day of the first reporting period following the change in the business model. FINANCIAL ASSETS MEASUREMENT Amortized cost A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as at FVTPL: •   it is held within a business model that has the objective of holding assets to collect contractual cash flows; and •   its contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. Debt investment A debt instrument is measured at FVTOCI only if it meets both of the following conditions and is not designated as at FVTPL: •   it is held within a business model that has the objective of both collecting contractual cash flows and selling financial assets; and •   its contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. Equity investment On initial recognition of an equity investment that is not held for trading, PEMEX may irrevocably elect to present subsequent changes in fair value in OCI. This election is made on an investment-by-investment basis. All financial assets not classified as measured at amortized cost or FVTOCI (as described above) are measured at FVTPL. This includes all derivative financial assets (see Note 18). On initial recognition, PEMEX may irrevocably designate a financial asset that otherwise meets the requirements to be measured at amortized cost or at FVOCI as FVTPL, if doing so eliminates or significantly reduces an accounting mismatch that would otherwise arise. Financial assets: Business model assessment PEMEX assesses the objective of the business model in which a financial asset is held at a portfolio level because this best reflects the way the business is managed and information is provided to management. The information considered includes: • the stated policies and objectives for the portfolio and the operation of those policies in practice, which include whether management’s strategy focuses on earning contractual interest income, maintaining a particular interest rate profile, matching the duration of the financial assets to the duration of any related liabilities or expected cash outflows or realizing cash flows through the sale of the assets; • how the performance of the portfolio is evaluated and reported to PEMEX management; • the risk that affects the performance of the business model (and the financial assets held within that business model) and how those risks are managed; • how managers of the business are compensated (e.g., whether compensation is based on the fair value of the assets managed or the contractual cash flows collected); and • the frequency, volume and timing of sales in prior periods, the reasons for such sales and expectations about future sales activity. Transfers of financial assets to third parties in transactions that do not qualify for derecognition are not considered sales for this purpose, consistent with PEMEX’s continuing recognition of the assets. Financial assets that are held for trading or managed and the performance of which is evaluated on a fair value basis are measured at FVTPL. Financial Asset: Assessment whether contractual cash flows are solely payments of principal and interest For the purposes of this assessment, principal is defined as the fair value of the financial assets on initial recognition. Interest is defined as consideration for the time value of money and for the credit risk associated with the principal amount outstanding during the relevant period of time and for the basic lending risks and costs (e.g., liquidity risk and administrative costs), as well as profit margin. In assessing whether the contractual cash flows are solely payments of principal and interest, PEMEX considers the contractual terms of the instrument, which includes assessing whether the financial asset contains a contractual term that could change the timing or amount of contractual cash flows such that it would not meet this condition. In making this assessment, PEMEX considers: • contingent events that would change the amount or timing of cash flows; • terms that may adjust the contractual coupon rate, including variable rate features; • prepayment and extension features; and • terms that limit PEMEX’s claim to cash flows from specified assets (for example, non-recourse features). A prepayment feature is consistent solely with the payments of principal and interest criterion if the prepayment amount substantially represents unpaid amounts of principal and interest on the principal amount outstanding, which may include reasonable additional compensation for early termination of the contract. Additionally, for a financial asset acquired at a significant discount or premium to its contractual par amount, a feature that permits or requires prepayment at an amount that substantially represents the contractual par amount plus accrued (but unpaid) contractual interest (which may also include reasonable additional compensation for early termination) is treated as consistent with this criterion if the fair value of the prepayment feature is insignificant at initial recognition. Financial assets: Subsequent measurement and gain and losses Financial assets at FVTPL Financial assets at FVTPL are measured at fair value and changes therein, including any interest or dividend income, are recognized in profit or loss. Financial assets at amortized cost These assets are subsequently measured at amortized cost using the effective interest method. The amortized cost is reduced by impairment losses. Interest income, foreign exchange gains and losses and impairment are recognized in profit or loss. Any gain or loss on derecognition is recognized in profit or loss. Debt investments at FVOCI These assets are subsequently measured at fair value. Interest income calculated using the effective interest method, foreign exchange gains and losses and impairment are recognized in profit or loss. Other net gains and losses are recognized in OCI. On derecognition, gains and losses accumulated in OCI are reclassified to profit or loss. Equity investments at FVOCI These assets are subsequently measured at fair value. Dividends are recognized as income in profit or loss unless the dividend clearly represents a recovery of part of the cost of the investment. Other net gains and losses are recognized in OCI and are never reclassified to profit or loss. Financial liabilities: Classification, subsequent measurement and gains and losses Financial liabilities are classified as measured at amortized cost or FVTPL. A financial liability is classified as FVTPL if it is classified as held-for-trading, it is a derivative or it is designated as such on initial recognition. Financial liabilities at FVTPL are measured at fair value and net gains and losses, including any interest expense, are recognized in profit or loss. Other financial liabilities are subsequently measured at amortized cost using the effective interest method. Interest expense and foreign exchange gains and losses are recognized in profit or loss. Any gain or loss on derecognition is also recognized in profit or loss. iii. Derecognition Financial assets PEMEX derecognizes a financial asset when the contractual rights to the cash flows from the financial asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all of the risks and rewards of ownership of the financial asset are transferred or in which PEMEX neither transfers nor retains substantially all of the risks and rewards of ownership and it does not retain control of the financial asset. PEMEX enters into transactions whereby it transfers assets recognized in its statement of financial position but retains either all or substantially all of the risks and rewards of the transferred assets. In these cases, the transferred assets are not derecognized. Financial liabilities PEMEX derecognizes a financial liability when its contractual obligations are discharged, cancelled or expired. PEMEX also derecognizes a financial liability when its terms are modified and the cash flows of the modified liability are substantially different, in which case a new financial liability based on the modified terms is recognized at fair value. On derecognition of a financial liability, the difference between the carrying amount extinguished and the consideration paid (including any non-cash assets transferred or liabilities assumed) is recognized in profit or loss. Interest rate benchmark reform When the basis for determining the contractual cash flows of a financial asset or financial liability measured at amortized cost changed as a result of interest rate benchmark reform, PEMEX updated the effective interest rate of the financial asset or financial liability to reflect the change that is required by the reform. A change in the basis for determining the contractual cash flows is required by interest rate benchmark reform if the following conditions are met: • the change is necessary as a direct consequence of the reform; and • the new basis for determining the contractual cash flows is economically equivalent to the previous basis – i.e., the basis immediately before the change. When changes are made to a financial asset or financial liability in addition to changes to the basis for determining the contractual cash flows required by interest rate benchmark reform, PEMEX first updates the effective interest rate of the financial asset or financial liability to reflect the change that is required by interest rate benchmark reform. After that, PEMEX applies the policies on accounting for modifications to the additional changes. iv. Offsetting Financial assets and financial liabilities are offset, and the net amount is presented in the statement of financial position when, and only when, PEMEX has a legally enforceable right to set off the amounts and it intends either to settle them on a net basis or to realize the asset and settle the liability simultaneously. v. Derivative financial instruments and hedge accounting PEMEX uses DFIs to hedge the risk exposure in foreign currency, interest rate and the price of commodities related to its products. Embedded derivatives are separated from the host contract and accounted for separately if the host contract is not a financial asset and certain criteria are met. These contracts are not accounted as designated hedging instruments. DFIs are accounted for as financial assets when the fair value is positive and as a financial liability when the fair value is negative. vi. Impairment Financial instruments and contract assets PEMEX recognizes loss allowances for Estimated Credit Losses (“ECLs”) on: • financial assets measured at amortized cost; • debt investments measured at FVOCI; and • contract assets. PEMEX measures loss allowances at an amount equal to lifetime ECL, except for the following, which are measured as 12-month ECLs: • debt securities that are determined to have low credit risk at the reporting date; and • other debt securities and bank balances for which credit risk (i.e., the risk of default occurring over the expected life of the financial instrument) has not increased significantly since initial recognition. PEMEX considers a financial asset to be in default when the debtor is unlikely to pay its credit obligations to PEMEX in full, without recourse by PEMEX to actions such as guarantee redemption (if any is held). PEMEX considers that a debt instrument has a low credit risk, when its credit rating is classified as “investment grade.” The investment grade classification is based on minimum credit ratings of Baa3 (Moody’s) and BBB- (S&P and Fitch), as well as its equivalent in other rating agencies. Lifetime ECLs are the credit losses that result from all possible default events over the expected life of a financial instrument. 12-month ECLs are the portion of ECLs that result from default events that are possible within the 12 months after the reporting date (or a shorter period if the expected life of the instrument is less than 12 months). The maximum period considered when estimating ECLs is the maximum contractual period over which PEMEX is exposed to credit risk. Measurement of ECLs ECLs are a probability-weighted estimate of credit losses. Credit losses are measured as the present value of all cash shortfalls (for example, the difference between the cash flows due to the entity in accordance with the contract and the cash flows that PEMEX expects to receive). ECLs are discounted at the effective interest rate of the financial asset. Credit-impaired financial assets At each reporting date, PEMEX assesses whether financial assets carried at amortized cost and debt securities at FVOCI are credit-impaired. A financial asset is ‘credit-impaired’ when one or more events that have a detrimental impact on the estimated future cash flows of the financial asset have occurred. Evidence that a financial asset is credit-impaired includes the following observable data: • significant financial difficulty of the borrower or issuer; • a breach of contract such as a default or being more than 90 days past due; • the restructuring of a loan or advance by PEMEX on terms that it would not consider otherwise; • it is probable that the borrower will enter bankruptcy or other financial reorganization; or • the disappearance of an active market for a security because of financial difficulties. Presentation of allowance for ECL in the statement of financial position Loss allowances for financial assets measured at amortized cost are deducted from the gross carrying amount of the assets. Write-off The gross carrying amount of a financial asset is written off when PEMEX has no reasonable expectation of recovering a financial asset in its entirety or a portion thereof. In the case of individual customers, PEMEX’s policy is to cancel the gross carrying amount when the financial asset has met the uncollectibility report as established in the Políticas Generales y Procedimientos para Cancelar Adeudos (Procedure to Write-Off Financial Assets). For corporate customers, PEMEX individually makes an assessment with respect to the timing and amount of write-off based on whether there is a reasonable expectation of recovery. However, financial assets that are written off could still be subject to enforcement activities in order to comply with the PEMEX’s procedures for recovery of amounts due.
Inventories and cost of sales	D. Inventories and cost of sales Inventories are valued at the lower of cost or net realizable value. Cost is determined based on the cost of production or acquisition of inventory and other costs incurred in transporting such inventory to its present location and in its present condition, using the average cost method. Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated selling costs. The estimate takes into consideration, among other things, the decrease in the value of inventories due to obsolescence. Cost of sales represents the cost of production or acquisition of inventories at the time of sale, increased, where appropriate, by declines in net realizable value of inventories during the year. Advance payment to suppliers for inventory purchases are recognized as part of inventory when the risks and benefits of the ownership of the inventory have been transferred to PEMEX.
Wells, pipelines, properties, plant and equipment	E. Wells, pipelines, properties, plant and equipment i. Recognition and measurement Items of wells, pipelines, properties, plant and equipment are recorded at acquisition or construction cost, which includes capitalized borrowing cost, less accumulated depreciation and accumulated impairment losses. Initial costs of wells, pipelines, properties, plant and equipment are initially recorded at cost, which includes their original purchase price or construction cost, any costs attributable to bringing the assets to a working condition for their intended use and the costs of dismantling and removing the items and restoring the site on which they are located, including the estimated cost of plugging and abandoning wells. The cost of financing projects that require large investments and financing incurred for projects, net of interest revenues from the temporary investment of these funds, is recognized as part of wells, pipelines, properties, plant and equipment when the cost is directly attributable to the construction or acquisition of a qualifying asset. The capitalization of these costs is suspended during periods in which the development of construction is interrupted, and its capitalization ends when the activities necessary for the use of the qualifying asset are substantially completed. All other financing costs are recognized in the consolidated statements of comprehensive income in the period in which they are incurred. The cost of self-constructed assets includes the cost of materials and direct labor, interest on financing and any other costs directly attributable to start up. In some cases, the cost also includes costs of plugging of wells and removal at present value. Expenditures related to the construction of wells, pipelines, properties, plant and equipment during the stage prior to commissioning are stated at cost as intangible assets or construction in progress, in accordance with the characteristics of the asset. Once the assets are ready for use, they are transferred to the respective component of wells, pipelines, properties, plant and equipment and depreciation or amortization begins. If significant parts of an item of wells, pipelines, properties, plant and equipment have different useful lives, then they are accounted for as separate items (major components) of property, plant and equipment. Any gain or loss on disposal of an item of wells, pipelines, properties, plant and equipment is recognized in profit or loss. Advance payments for the acquisition of pipelines, properties, plant and equipment are also recognized in the line item of wells, pipelines, properties, plant and equipment when the risks and benefits of the ownership have been transferred to PEMEX. ii. Subsequent expenditure The costs of major maintenance or replacement of a significant component of an item of wells, pipelines, properties, plant and equipment are recognized in the carrying amount of the item if it is probable that the future economic benefits embodied within the component will flow to PEMEX and its cost can be measured reliably. The costs of recurring maintenance, repairs and renovations of wells, pipelines, properties, plant and equipment carried out to maintain the facilities in normal operation conditions are recognized in profit or loss as incurred. iii. Depreciation Depreciation and amortization of capitalized costs in wells are determined based on the estimated economic life of the field to which the wells belong, considering the relationship between the production of barrels of oil equivalent for the period and proved developed reserves of the field, as of the beginning of the period, with quarterly updates for new development investments. Depreciation of other elements of pipelines, properties, plant and equipment is recognized in profit or loss on a straight-line basis over the estimated useful life of the asset, beginning as of the date that the asset is available for use, or in the case of construction, from the date that the asset is completed and ready for use. The estimated useful lives of wells, pipelines, properties, plant and equipment for current and comparative periods are described in Note 13. Estimated useful lives of items of properties, plant and equipment are reviewed and updated prospectively if expectations differ from previous estimates.
Intangible assets and oil and natural gas exploration and license, appraisal and development expenditure	F. Intangible assets and oil and natural gas exploration and license, appraisal and development expenditure i. Intangible assets Intangible assets acquired separately are measured at initial recognition at their acquisition cost. After the initial recognition, intangible assets are valued at their acquisition cost, less: (i) accumulated amortization, under the straight-line method during the estimated useful life of the intangible asset and (ii) accumulated impairment losses. Subsequent expenditure is capitalized only when it increases the future economic benefits embodied in the specific asset to which it relates. All other expenditure is recognized in profit or loss as incurred. Amortization is calculated to write off the cost of intangible assets less their estimated residual values using the straight-line method over their estimated useful lives and is generally recognized in profit or loss. Software licenses are amortized over the lesser of their contract period or the remaining life of the asset to which they are associated. The estimated useful lives of elements of intangible assets for current and comparative periods are described in Note 14. The estimated useful lives and residual values of intangible assets are reviewed at each reporting date and adjusted if appropriate. ii. Wells not assigned to a reserve, oil and natural gas exploration, appraisal and development expenditure a. Wells not assigned to a reserve Wells not assigned to a reserve mainly include drilling, evaluation and development costs for oil and natural gas, and rights-of-way. b. Oil and natural gas exploration, appraisal and development expenditures Oil and natural gas exploration, evaluation and development expenses are accounted for using the principles of the successful efforts method of accounting, as described below: Successful Efforts Method Pemex Exploration and Production applies IFRS 6 - Exploration and Evaluation of Mineral Resources, which allows an entity to develop an accounting policy for exploration and evaluation assets. Therefore, Pemex Exploration and Production uses the method of successful efforts, which requires a cause-and-effect relationship between the costs incurred and the recognition of specific reserves. Generally, if a cost is incurred without an identifiable future benefit, it is charged to expenses. Before PEMEX is able to determine the accounting treatment of a cost, it must be classified as a property acquisition, exploration, development or production cost. Exploration and appraisal expenditure Geological and geophysical exploration costs including topographic costs, geological studies, property access rights, remuneration and expenses of geologists and geophysicists are charged to expenses as incurred. Costs directly associated with an exploration well, other than the costs mentioned in the preceding paragraph, are initially capitalized as an intangible asset (wells not assigned to a reserve) until the drilling of the well is complete and the results have been evaluated. These costs include employee compensation, materials and fuel used, platform costs and payments made to contractors. If potentially commercial quantities of hydrocarbons are not found, the exploration well costs are written off against profit or loss. If hydrocarbons are found and, subject to additional assessment activity, are likely to be capable of commercial development, the costs continue to be carried as an asset. If it is determined that development will not occur, then the costs are expensed against profit or loss. Costs directly associated with the evaluation activity performed to determine the size, characteristics and commercial potential of a reserve after the initial hydrocarbon discovery, including the costs of evaluation of wells where no hydrocarbons were found, are initially capitalized as an intangible asset (wells not assigned to a reserve). When proved reserves of oil and natural gas are determined and development is approved by management, the relevant expenditure is transferred to wells, pipelines, properties, plant and equipment. Exploration wells more than 12 months old are recognized as an expense unless: (a)(i) they are in an area requiring major capital expenditure before production can begin, (ii) commercially productive quantities of reserves have been found, and (iii) they are subject to further exploration or appraisal activity, in that, either drilling or additional exploration wells are underway or firmly planned for the near future or (b) proved reserves are viable within 12 months of completion of the exploratory drilling. Development expenditure Expenditure on the construction, installation and completion of infrastructure facilities such as platforms, pipelines and the drilling of development wells, including service and unsuccessful development or delineation wells, is capitalized within wells, pipelines, properties, plant and equipment and is depreciated from the commencement of production as described in the accounting policy for wells, pipelines, properties, plant and equipment. Exploration Exploration includes all expenses related to the search for oil and / or gas reserves, including depreciation and applicable costs of supporting equipment and facilities, and the costs of drilling exploratory wells and exploratory stratigraphic wells. Some exploration costs are charged directly to expenses when they occur, such as the costs of maintaining unexploited properties, since such costs do not increase the possibilities that said lands contain proven reserves. The costs of geologists, topographers and geophysicists, including wages and other related expenses, are also charged directly to expenses when they occur because they do not represent the acquisition of an identifiable asset since these studies represent research expenses. All costs for drilling exploratory wells are capitalized and classified as wells, pipelines, property, plant and equipment, not associated with a reserve, until it is determined whether or not a well has proven reserves. Once the exploratory wells are completed, the future treatment of these costs is determined. Development Development costs are associated with previously discovered proven reserves, with previously known future benefits. Therefore, all costs incurred in development activities must be capitalized. Development includes all costs incurred in creating a system of productive wells, related equipment, and facilities in proven reserves so that oil and / or gas can be extracted. Developmental costs are related to specific proven reserves. The cost of building roads to gain access to proven reserves is a development cost, as is the cost of providing facilities for the extraction, treatment, collection and storage of oil and / or gas. Developmental costs also include depreciation and operating costs of equipment and facilities used in developmental activities. Likewise, non-productive development wells are capitalized, since they are considered as a cost of creating the total production system for proven reserves. Production Production includes the costs incurred to raise oil and / or gas to the surface, its collection, treatment, processing and field storage.
Crude oil and natural gas reserves	G. Crude oil and natural gas reserves Under Mexican law, all crude oil and other hydrocarbon reserves located in the subsoil of Mexico are owned by the Mexican nation and not by PEMEX. In accordance with the aforementioned and based on the applicable regulation as of the date of these consolidated financial statements, the reserves assigned to PEMEX by the Mexican Government are not registered for accounting purposes because they are not PEMEX’s property. PEMEX estimates total proved oil and natural gas reserve volumes in accordance with the definitions, methods and procedures established in Rule 4-10(a) of Regulation S-X (“Rule 4-10(a)”) of the U.S. Securities and Exchange Commission (“SEC”), as amended, and where necessary, in accordance with the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers (the “SPE”) as of February 19, 2007. These procedures are consistent with international reserves reporting practice. The estimation of these reserves depends on assumptions made and the interpretation of the data available and may vary among analysts. The results of drilling activities, test wells and production after the date of estimation are utilized in future revisions of reserves estimates. Although PEMEX does not own the oil and other hydrocarbon reserves within Mexico, these procedures allow PEMEX to record the effects that such oil and other hydrocarbon reserves have on its consolidated financial statements, including, for example, in the depreciation and amortization line item.
Impairment of non-financial assets	H. Impairment of non-financial assets The carrying amounts of PEMEX’s non-financial assets, other than inventories and deferred taxes, are assessed for indicators of impairment at the end of each reporting period. If the net carrying value of the asset or its cash-generating unit exceeds the recoverable amount, PEMEX records an impairment charge in profit or loss. A cash-generating unit is the smallest identifiable group of assets which can generate cash flows independently from other assets or groups of assets. The recoverable amount of an asset or a Cash-Generating Unit (“CGU”) is defined as the higher of its fair value minus the costs of disposal and its value in use. The value in use is the discounted present value of the net future cash flows expected to arise from the continuing use of an asset and from its disposal at the end of its useful life. In measuring value in use, the discount rate applied is the pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the asset. Fair value is calculated using discounted cash flows determined by the assumptions that market participants would apply in order to estimate the price of an asset or CGU, assuming that such participants were acting in their best economic interest. In the case of cash-generating assets or items dedicated to the exploration and evaluation of hydrocarbons reserves, the recoverable amount is determined using the value in use based on the proved reserves and probable reserves, in some cases, for the risk factor associated with such reserves. Both impairment losses and reversals are recognized in the statement of comprehensive income in the costs and expenses line items in which the depreciation and amortization are recognized. Impairment losses may not be presented as part of the costs that have been capitalized in the value of any asset. Impairment losses related to inventories are recognized as part of cost of sales. Impairment losses on investments in associates, joint ventures and other investments are recognized as profit (loss) sharing in associates. An impairment loss shall be reversed if there has been a change in the estimates used since the date when the impairment loss was recognized. These reversals will not exceed the carrying value of the asset as though no impairment had been recognized. Impairment losses and reversals are presented in a separate line item in the consolidated statement of comprehensive income.
Leases	I. Leases At the inception of a contract, PEMEX assesses whether a contract is, or contains, a lease. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. To assess whether a contract conveys the right to control the use of an identified asset, PEMEX uses the definition of a lease in IFRS 16. i. As a lessee At commencement or on modification of a contract that contains a lease component, PEMEX allocates the consideration in the contract to each lease component on the basis of its relative stand-alone prices. However, PEMEX has elected for some leases not to separate non-lease components and to account for the lease and non-lease components as a single lease component. PEMEX recognizes a right-of-use asset and a lease liability at the lease commencement date. The right-of-use asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred and an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset or the site on which it is located, less any lease incentives received. The right-of-use asset is subsequently depreciated using the lesser of the straight-line method and the hours of use method, from the commencement date to the end of the lease term, unless the lease transfers ownership of the underlying asset to PEMEX by the end of the lease term or the cost of the right-of-use asset reflects that PEMEX will exercise a purchase option. In that case, the right-of-use asset will be depreciated over the useful life of the underlying asset, which is determined on the same basis as those of property and equipment. In addition, the right-of-use asset is periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability. Useful lives are shown in Note 17. The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, PEMEX’s incremental borrowing rate. Generally, PEMEX uses its incremental borrowing rate as the discount rate. PEMEX determines its incremental borrowing rate by obtaining interest rates from various external financing sources and makes certain adjustments to reflect the terms of the lease and type of the asset leased. Lease payments included in the measurement of the lease liability comprise the following: • fixed payments, including in-substance fixed payments; • variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the commencement date; • amounts expected to be payable under a residual value guarantee; and • the exercise price under a purchase option that PEMEX is reasonably certain to exercise, lease payments in an optional renewal period if PEMEX is reasonably certain to exercise an extension option, and penalties for early termination of a lease unless PEMEX is reasonably certain not to terminate early. The lease liability is measured at amortized cost using the effective interest method. It is remeasured when there is a change in future lease payments arising from a change in an index or rate, if there is a change in PEMEX’s estimate of the amount expected to be payable under a residual value guarantee, if PEMEX changes its assessment of whether it will exercise a purchase, extension or termination option or if there is a revised in-substance fixed lease payment. When the lease liability is remeasured in this way, a corresponding adjustment is made to the carrying amount of the right-of-use asset or is recorded in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero. From January 1, 2021, PEMEX began remeasuring its lease liability by discounting the revised lease payments using the revised discount rate that reflects the change to an alternative benchmark interest rate. This change reflects the requirements of the interest rate benchmark reform, which adjusted the basis for determining future lease payments. PEMEX presents separately the right-of-use assets and lease liabilities in the statement of financial position. Short-term leases and leases of low-value assets PEMEX has elected not to recognize right-of-use assets and lease liabilities for leases of low-value assets and short-term leases. PEMEX recognizes the lease payments associated with these leases as an expense on a straight-line basis over the lease term. ii. As a lessor At inception or upon modification of a contract that contains a lease component, PEMEX allocates the consideration in the contract to each lease component on the basis of their relative stand-alone prices. When PEMEX acts as a lessor, it determines at lease inception whether each lease is a finance lease or an operating lease. To classify each lease, PEMEX makes an overall assessment of whether the lease transfers substantially all of the risks and rewards incidental to ownership of the underlying asset. If this is the case, then the lease is a finance lease; if not, then it is an operating lease. As part of this assessment, PEMEX considers certain indicators such as whether the lease is for the major part of the economic life of the asset. If an arrangement contains lease and non-lease components, then PEMEX applies IFRS 15 to allocate the consideration in the contract. PEMEX applies the derecognition and impairment requirements in IFRS 9 to the net investment in the lease. Further, PEMEX regularly reviews estimated unguaranteed residual values used in calculating the gross investment in the lease. PEMEX recognizes lease payments received under operating leases as income on a straight-line basis over the lease term as part of “other revenue.”
Provisions	J. Provisions Provisions are determined by discounting the expected future cash flows at a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the liability. The unwinding of the discount is recognized as finance cost. PEMEX recognizes provisions when, as a result of a past event, PEMEX has incurred a legal or assumed present obligation for which a future disbursement is probable and the value of such disbursement is reasonably estimable. In certain cases, such amounts are recorded at their present value. Increases in ongoing legal expense liabilities are recognized in the Consolidated Statement of Comprehensive Income in the “Other expenses” line item. Environmental liabilities In accordance with applicable legal requirements and accounting practices, an environmental liability is recognized when the cash outflows are probable and the amount is reasonably estimable. Disbursements related to the conservation of the environment that are linked to revenue from current or future operations are accounted as expenses or assets, depending on the circumstances of each disbursement. Disbursements related to past operations, which no longer contribute to current or future revenues, are accounted for as current period expenses. The accrual of a liability for a future disbursement occurs when an obligation related to environmental remediation, for which PEMEX has the information necessary to determine a reasonable estimated cost, is identified. Increases in environmental liabilities are recognized in the Consolidated Statement of Comprehensive Income in the “Cost of sales” line item. Retirement of assets The obligations associated with the future retirement of assets, including those related to the retirement of wells, pipelines, properties, plant and equipment and their components are recognized at the date that the retirement obligation is incurred, based on the discounted cash flow method. The determination of the fair value is based on existing technology and regulations. If a reliable estimation of fair value cannot be made at the time the obligation is incurred, the accrual will be recognized when there is sufficient information to estimate the fair value. The obligations related to the costs of future retirement of assets associated with the principal refining processes for gas and petrochemicals are not recognized. These assets are considered to have an indefinite useful life due to the potential for maintenance and repairs. The abandonment costs related to wells currently in production and wells temporarily closed are recorded in the statement of comprehensive income based on the units of production method. Total cost of abandonment and plugging for non-producing wells is recognized in the statement of comprehensive income at the end of each period. All estimations are based on the useful lives of the wells, considering their discounted present value. Salvage values are not considered, as these values commonly have not traditionally existed. Increases in retirement of assets liabilities are recognized as part of the cost of completed wells in fixed assets.
Employee benefits	K. Employee benefits i. Short-term employee benefits Short-term employee benefits are expensed as the related service is provided. A liability is recognized for the amount expected to be paid if PEMEX has a present legal or constructive obligation to pay this amount as a result of past service provided by the employee and the obligation can be estimated reliably. ii. Defined contribution plans Obligations for contributions to defined contribution plans are expensed as the related service is provided. Prepaid contributions are recognized as an asset to the extent that a cash refund or a reduction in future payments is available. iii. Defined benefit plan PEMEX’s net obligation in respect of defined benefit plans is calculated separately for each plan by estimating the amount of future benefit that employees have earned in the current and prior periods, discounting that amount and deducting the fair value of any plan assets. The calculation of defined benefit obligations is performed annually by a qualified actuary using the projected unit credit method. When the calculation results in a potential asset for PEMEX, the recognized asset is limited to the present value of economic benefits available in the form of any future refunds from the plan or reductions in future contributions to the plan. To calculate the present value of economic benefits, consideration is given to any applicable minimum funding requirements. New remeasurements of the net defined benefit liability, which comprise actuarial gains and losses, the return on plan assets (excluding interest) and the effect of the asset ceiling (if any, excluding interest), are recognized immediately in OCI. PEMEX determines the net interest expense (income) on the net defined benefit liability (asset) for the period by applying the discount rate used to measure the defined benefit obligation at the beginning of the annual period to the net defined benefit liability (asset) at such time, considering any changes in the net defined benefit liability (asset) during the period as a result of contributions and benefit payments. Net interest expense and other expenses related to defined benefit plans are recognized in profit or loss. When the benefits of a plan are changed or when a plan is curtailed, the resulting change in benefit that relates to past service or the gain or loss on curtailment is recognized immediately in profit or loss. PEMEX recognizes gains and losses from the settlement of a defined benefit plan when the settlement occurs. iv. Other long-term employee benefits PEMEX’s net obligation in respect of long-term employee benefits is the amount of future benefit that employees have earned in return for their service in the current and prior periods. That benefit is discounted to determine its present value. New remeasurements are recognized in profit or loss in the period in which they arise. v. Termination benefits Termination benefits are expensed at the earlier of when PEMEX can no longer withdraw its offer of those benefits and when PEMEX recognizes costs for a restructuring. If benefits are not expected to be settled in full within 12 months of the reporting date, then they are discounted.
Income taxes, duties and royalties	L. Income taxes, duties and royalties Income tax expense comprises current and deferred tax. It is recognized in profit or loss except to the extent that it relates to a business combination, or items recognized directly in equity or in OCI. The interest and penalties related to income taxes, including uncertain tax treatments, do not meet the definition of income taxes, and are therefore accounted for under IAS 37 “Provisions, Contingent Liabilities and Contingent Assets.” i. Current income tax Current income tax comprises the expected tax payable or receivable on the taxable income or loss for the year and any adjustment to the tax payable or receivable in respect of previous years. The amount of current tax payable or receivable is the best estimate of the tax amount expected to be paid or received that reflects uncertainty related to income taxes, if any. It is measured using tax rates enacted or substantively enacted at the reporting date. Current tax also includes any tax arising from dividends. Current tax assets and liabilities are offset only if certain criteria are met. ii. Deferred income tax Deferred income tax is recognized in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. Deferred tax is not recognized for: • temporary differences on the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither accounting nor taxable profit or loss; • temporary differences related to investments in subsidiaries, associates and joint arrangements to the extent that PEMEX is able to control the timing of the reversal of the temporary differences and it is probable that they will not reverse in the foreseeable future; and • taxable temporary differences arising from the initial recognition of goodwill. Temporary differences in relation to a right-of-use asset and a lease liability for a specific lease are regarded as a net package (the lease) for the purpose of recognizing deferred tax. Deferred tax assets are recognized for unused tax losses, unused tax credits and deductible temporary differences to the extent that it is probable that future taxable profits will be available against which they can be used. Future taxable profits are determined based on the reversal of relevant taxable temporary differences. If the amount of taxable temporary differences is insufficient to recognize a deferred tax asset in full, then future taxable profits, adjusted for reversals of existing temporary differences, are considered, based on the business plans of PEMEX. Deferred tax assets are reviewed at each reporting date and are reduced to the extent that it is no longer probable that the related tax benefit will be realized. Such reductions are reversed when the probability of future taxable profits improves. Unrecognized deferred tax assets are reassessed at each reporting date and recognized to the extent that it has become probable that future taxable profits will be available against which they can be used. Deferred tax is measured at the tax rates that are expected to be applied to temporary differences when they reverse, using tax rates enacted or substantively enacted at the reporting date. The measurement of deferred tax reflects the tax consequences that would follow from the manner in which PEMEX expects, at the reporting date, to recover or settle the carrying amount of its assets and liabilities. Deferred tax assets and liabilities are offset only if certain criteria are met. iii. Duties, royalties and considerations Duties PEMEX is subject to taxes and special duties, which are based on the value of hydrocarbons extracted, with certain deductions. These taxes and duties are recognized in accordance with IAS 12 “Income Taxes” (IAS 12) when they have the characteristics of income tax, which occurs when such taxes are set by a government authority and are determined based on a formula that considers the balance of income (or extraction valued at a selling price) less expenses. Taxes and duties that meet these criteria are recognized for current and deferred income tax based on the above paragraphs. Taxes and duties that do not meet these criteria are recognized in costs and expenses relating to the transactions that gave rise to them. Royalties and considerations
Contingencies	M. Contingencies Contingency losses are recorded when it is probable that a liability has been incurred and the amount thereof can be reasonably estimated. When a reasonable estimation cannot be made, qualitative disclosure is provided in the notes to the consolidated financial statements. Contingent assets are not recognized until realization is assured.
Government grants (Revenues from FONADIN)	N. Government grants (Revenues from FONADIN) Government grants related to assets are initially recognized as deferred income at fair value if there is reasonable assurance that they will be received and PEMEX will comply with the conditions associated with the grant. Grants related to the acquisition of assets are recognized in profit or loss as other income on a systematic basis over the useful life of the asset.
Fair value	O. Fair value ‘Fair value’ is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in the principal or, in its absence, the most advantageous market to which PEMEX has access at that date. The fair value of a liability reflects its non-performance risk. A number of PEMEX accounting policies and disclosures require the measurement of fair values, for both financial and non-financial assets and liabilities (see Note 8). When one is available, PEMEX measures the fair value of an instrument using the quoted price in an active market for that instrument. A market is regarded as ‘active’ if transactions for the asset or liability take place with sufficient frequency and volume to provide pricing information on an ongoing basis. If there is no quoted price in an active market, then PEMEX uses valuation techniques that maximize the use of relevant observable inputs and minimize the use of unobservable inputs. The chosen valuation technique incorporates all of the factors that market participants would take into account in pricing a transaction. If an asset or a liability measured at fair value has a bid price and an ask price, then PEMEX measures assets and long positions at the bid price and liabilities and short positions at the ask price.
Revenue from contracts with customers	P. Revenue from contracts with customers Revenue is measured based on the consideration specified in a contract with a customer. PEMEX recognizes revenue when it transfers control over a good or service to a customer. The transaction price is established at the time of sale, including the estimate of the variable consideration (see Note 7).
Operating segments	Q. Operating segments Operating segments are identifiable components of PEMEX that pursue business activities from which PEMEX earns revenues and incurs expenses and for which information is available to management on a segmented basis and is assessed by the Board of Directors in order to allocate resources and assess the profitability of the segments.
Presentation of consolidated statements of comprehensive income	R. Presentation of consolidated statements of comprehensive income Costs and expenses shown in PEMEX’s consolidated statements of income are presented based on their function, which allows for a better understanding of the components of PEMEX’s operating income. This classification allows for a comparison to the industry to which PEMEX belongs. i. Operating profit Operating profit is the result generated from the continuing principal revenue-producing activities of PEMEX as well as other income and expenses related to operating activities. Operating profit excludes net finance costs, share of profit of equity-accounted investees and income taxes and duties. Revenues Represents revenues from the sale of products or services. Cost of sales Cost of sales represents the acquisition and production costs of inventories, depreciation, amortization, salaries, wages and benefits, a portion of the cost of the reserve for employee benefits and operating expenses related to the production process, production taxes and duties, impairment, exploration costs, non-operating costs, among others. Other revenues and other expenses Other revenues and other expenses consist primarily of income and expenses that are not related directly to the operation of PEMEX. Transportation, distribution and sale expenses Transportation, distribution and sale expenses are costs in connection with the storage, sale and delivery of products, such as the depreciation and operating expenses associated with these activities. Administrative expenses Administrative expenses are costs related to PEMEX’s areas that provide administrative support. ii. Financing income and financing cost and derivative financial instruments income (cost), net Financing income Financing income is comprised of interest income, financial income and other income from financial operations between PEMEX and third parties. Financing cost Financing cost is comprised of interest expenses, commissions and other expenses related to PEMEX’s financing operations less any portion of the financing cost that is capitalized. When calculating interest income and expenses, the effective interest rate is applied to the gross carrying amount of the asset (when the asset has no credit impairment), to the amortized cost of the liability or to the present value lease liabilities. However, for financial assets with credit impairment after initial recognition, interest income is calculated by applying the effective interest rate at the amortized cost of the financial asset. If the asset ceases to be impaired, the interest income calculation returns to the gross base. Derivative financial instruments (cost) income, net Includes the result of changes in the fair value of derivative financial instruments (see note 18).
Incentive for automotive fuels	S. Incentive for automotive fuels On March 3, 2022, the federal government issued a decree that established a tax incentive applicable to entities subject to the Impuesto Especial sobre Producción y Servicios (Special Tax on Production and Services). Pursuant to this stimulus, PEMEX can recover the difference between the international reference price of gasoline and the price at which the gasoline is traded in the domestic market. This stimulus is known as the "automotive incentive." The decree quantifies the automotive incentive based on the volume of fuel sold by applying a rate issued by the SHCP on a weekly basis. The decree also refers to the general rules issued by the SHCP that dictate the procedures to request the amount of the automotive incentive. The automotive incentive is measured based on the volume sold and the rates authorized in accordance with the decree and is recognized as income when the customer obtains control of the fuel when it is delivered to its facilities. At the same time, a revenue and an account receivable from the SHCP are recognized. The application for the automotive incentive is generally submitted during the first 17 days of the month following the month in which the automotive incentive was generated and is recovered during the 30 days following the application. Pemex Industrial Transformation does not have any performance obligations to comply with in order to qualify for the automotive incentive, except for the sale of fuel to third parties, which is what gives rise to the incentive under the decree. Since fuel returns are not accepted, the automotive incentive does not require these considerations in its quantification. Pursuant to the decree, the automotive incentive is not subject to the Impuesto sobre la Renta (Income Tax Law), and therefore it is considered non-cumulative income for the purposes of the Income Tax Law .
Renewable fuels obligation	T. Renewable fuels obligation PEMEX is required to comply with the Renewable Fuel Standard implemented by the U.S. Environmental Protection Agency (“EPA”), which sets annual quotas for the quantity of renewable fuels (such as ethanol) that must be blended into motor fuels consumed in the United States. PEMEX’s renewable fuels obligations are based on a percentage of domestic product shipments as established by the EPA. PEMEX is required to purchase Renewable Identification Numbers (“RINs”). To the extent PEMEX is unable to blend the required amount of biofuels to satisfy its RINs obligations, PEMEX must purchase RINs on the open market to avoid penalties and fines. PEMEX accounts for its renewable fuels obligations on a net basis in Accrued expenses when its RINs liability is greater than the amount of RINs purchased in a given period and in Prepaid and other current assets when the amount of RINs earned and purchased is greater than the RINs obligations accrued during the year.
